condformat 0.11.0.9000

Bug fixes

• Applying a rule whose column selection matches no columns (e.g. an empty tidyselect match) no longer emits a spurious "cf key NULL is not supported" warning.

Tests

• Substantially increased internal test coverage (shiny.R, theme_htmlWidget.R, theme_htmlTable.R, rule_text_bold.R, render_html.R, condformat_render.R, theme_kable.R). No user-facing changes beyond the bug fix above.

condformat 0.11.0 (2026-07-09)

Breaking changes

• Drop the magrittr dependency and the %>% pipe operator it re-exported (part of #43). condformat now requires R >= 4.1 and its own examples, tests and vignette use the native base R pipe (|>) instead. If your code relied on library(condformat) making %>% available, either library(magrittr) yourself or switch to |>.

Dependencies

• Move gridExtra, gtable, openxlsx and rmarkdown from Imports to Suggests. These are each only needed for one specific, optional output path: openxlsx for condformat2excel()/condformat2excelsheet(), gridExtra/gtable for condformat2grob()/theme_grob(), and rmarkdown for LaTeX/PDF output via knit_print(). If you only ever use condformat's default HTML/RStudio-viewer printing, you no longer need to install any of these. Calling one of the functions above without the corresponding package installed now stops with a clear install.packages(...) hint instead of a generic "there is no package called" error, or (for rmarkdown) failing deep inside knit_print().
• Bump the minimum required version of all versioned dependencies to the release that was current about a year ago, rather than today's exact latest release, so users aren't forced onto a brand new patch just to install condformat (part of #43): dplyr (>= 1.1.4), gtable (>= 0.3.6), htmlTable (>= 2.4.3), htmltools (>= 0.5.8.1), knitr (>= 1.50), openxlsx (>= 4.2.8), rmarkdown (>= 2.29), rlang (>= 1.1.6), scales (>= 1.4.0), tibble (>= 3.3.0), tidyselect (>= 1.2.1), shiny (>= 1.11.1), testthat (>= 3.2.3) and vdiffr (>= 1.0.8). gridExtra's floor (>= 2.3) is unchanged, as that release is still the latest on CRAN as of a year ago.

New features

• rule_fill_bar() is now supported in Excel output, rendered using Excel's own native data bar conditional formatting (coloured with low) instead of being dropped with an "unsupported rule" warning. This only applies when expression is left at its default (or explicitly .col), since Excel data bars always reflect a cell's own displayed value against a range and can't replicate an arbitrary custom expression; in that case the data bar itself is skipped (with a warning) but the flat background/na.value cell colours are still applied, as before.
• Export condformat2excelsheet(), which writes a condformat table into a worksheet of an openxlsx workbook you're already building, without creating or saving the workbook itself (closes #25). Its docs show how to combine condformat's own cell styling with your own openxlsx::addStyle() calls (e.g. a number format) via stack = TRUE, since addStyle() replaces existing styles by default.
• Add a .col pronoun usable in the expression argument of rule_fill_discrete(), rule_fill_gradient(), rule_fill_gradient2(), rule_fill_bar(), rule_text_bold(), rule_text_color() and rule_css(). When columns selects more than one column, .col is bound to each column's own values in turn, so a single rule call can format several columns based on each one's own condition (closes #19): rule_fill_discrete(c(Sepal.Length, Sepal.Width), .col > 3) is now equivalent to chaining the rule once per column. expression now also defaults to .col when omitted, replacing the previous behaviour of silently using only the first selected column (with a warning) when no expression was given for a multi-column selection.

Fixes

• Fix condformat2excel()/condformat2excelsheet() silently discarding any pre-existing cell formatting on every export — including a Date column's automatic format from openxlsx::writeData() — even for cells with no condformat rule applied to them. condformat2excelsheet()'s own styling now uses stack = TRUE internally, so it merges with, rather than replaces, formatting that was already there (related to #25).
• Fix lockcells = TRUE being ignored (or worse, unlocking cells) for LaTeX and grob/gtable output in rule_fill_discrete(), rule_fill_gradient(), rule_fill_gradient2(), rule_text_bold() and rule_text_color(). HTML and Excel output were not affected.
• Fix theme_htmlTable() discarding arguments accumulated from earlier theme_htmlTable() calls in the same pipeline, due to a %in% check against list values instead of list names.
• Fix rule_fill_bar()'s na.value never being applied to background-color in HTML output: the CSS mask used to gate that assignment already excluded NA cells, so the assignment was dead code.
• Fix rule_fill_bar() erroring in grob/gtable output when a value rescaled to exactly 0% of the bar width (colorRampPalette() can't return zero colours); such cells now render with just the background colour.
• Fix rule_fill_bar()'s lockcells = TRUE not protecting NA cells from later CSS/HTML rules, and not protecting any cell (NA or not) from later grob/gtable rules: the grob/gtable renderer painted every targeted cell unconditionally and never checked incoming lock state at all.
• Fix rule_text_bold(), rule_text_color() and rule_css() erroring when expression evaluates to a single (scalar) value on a table with more than one row, unlike rule_fill_discrete(), rule_fill_gradient(), rule_fill_gradient2() and rule_fill_bar(), which already recycled such values to every row.

Other

• Fix the bundled shiny example (inst/shinyexample/): requireNamespace() now passes quietly = TRUE, so it no longer prints a package-startup message every time the optional colourpicker dependency isn't installed. Also modernised the legacy shinyUI()/shinyServer() wrappers to the current ui <- ... / server <- function(input, output) {...} style.

condformat 0.10.1 (2023-10-08)

Fixes

• Fix theme_grob() documentation
• Updated URLs
• Register internal S3 methods
• Minor documentation formatting

condformat 0.10.0 (2022-11-26)

New features

• condformat2grob() function takes an optional draw=TRUE parameter which controls whether the grob is immediately drawn during the function call. draw=FALSE allows easier use in composite figures with gridExtra::grid.arrange() or ggpubr::ggarrange() (@interzoneboy, #31)

Other

• Replace tidyselect::vars_select() (questioning) with tidyselect::eval_select()
• Avoid drawing plots on tests, use vdiffr instead.

condformat 0.9.0 (2020-05-14)

Breaking changes

• The lazyeval API deprecated on condformat 0.6 has been dropped, only the tidy evaluation API remains. This fixes dplyr 1.0.0 test failures.

New features

• Excel output supports rule_text_bold and rule_text_color

Deprecation

• space is ignored and deprecated in rule_fill_gradient and rule_fill_gradient2, following recent changes in the scales package. Please remove it if you are using it, as it will be removed in a future version

Other

• Replace xlsx with openxlsx. This avoids pulling RJava as a suggested dependency
• Warn if unsupported rule is used with Excel output
• Fix warning due to rlang update
• Change examples and tests so they don't open browser windows

condformat 0.8.0 (2018-10-29)

New features:

• rule_fill_bar (HTML, for now)
• rule_text_bold (HTML, PDF)
• rule_text_color (HTML, PDF)
• theme_htmlWidget (HTML) Customize the number of entries and the widget size.
• theme_kable (PDF) pass options to kable
• theme_caption (HTML, PDF) Set a caption.
• condformat2grob: Engine to render tables as graphics
• Shiny: renderCondformat works with "async" promises (if htmlwidgets 1.3 is available)

Deprecations:

• Deprecate: theme_htmlTable now only accepts arguments to be passed to htmlTable::htmlTable. Before, it could also be used to accept number_of_entries, width, height... to customize the widget appearance. For that use case, please use theme_htmlWidget instead.
• Deprecate: condformat2widget will not accept arguments to customize the appearance of the widget. Use theme_htmlWidget instead.

Other

• Replace dependency: Use grDevices instead of gplots
• Depend on knitr 1.18: slidy and other rmarkdown formats are properly detected (#13)
• Drop rJava from suggests (xlsx fix released)
• Bump rlang dependency (parse_quosure -> parse_expr) (#18, Thanks to @lionel- for the advice and code review!)
• Internal: More modular code. CSS tags to LaTeX conversion is based on S3 methods so new rules don't need to touch the code for LaTeX export.

condformat 0.7.0 (2017-10-19)

• Add a new condformat API, that is based on tidy evaluation principles and leverages on rlang and tidyselect. The old API is still fully functional but deprecated.
• Add a rule_css to let the user specify arbitrary CSS fields. For this rule there is no support for PDF or Excel output.
• Improve condformat2excel to export to a specific Excel sheet (#11)
• Fix condformat2latex and add regression test (#9)
• Fix rescale and rescale_mid calls (recent scales use a S3 generic, so we need to import it)

condformat 0.6.0 (2017-05-18)

• Fix tibble formatting issues, causing package malfunction.
• Fix: theme_htmlTable() now accepts the css.cell argument (thanks to 鱼飞灰 for reporting it)
• Require latest htmlTable. Improve/fix printing of condformat

condformat 0.5.0 (2017-01-23)

• Shiny support: Add condformatOutput and renderCondformat. Closes #3.
  • Use pagination in shiny if recent enough htmlTable package is installed.
• PDF support: Fix extra NULL when printing. Closes #4.
• Demote xlsx (and rJava) to Suggests.
• Fix standard evaluation functions, they now use formulas. See the examples (Reported in #5).
• Fix Excel export (fixed in 80440ecfd16fb74e3e0aa4c6ebc623ad2ae74b15, reported in #7)

condformat 0.4.0 (2016-07-25)

• Excel export support with condformat2excel

condformat 0.3.0

• PDF support: Export table to LaTeX using knitr.
• Fix examples for full compatibility with dplyr 0.5.0

condformat 0.2.0 (2016-03-07)

• First CRAN submission
• Add theme_htmlTable to pass custom formatting options to htmlTable.
• Improve knitr compatibility

condformat 0.1.1

• Change to a ggplot-like syntax
