Tables can now be exported to a wider variety of file formats using the flextabler package. Supported formats including Microsoft Word, Microsoft PowerPoint and PDF. See the Outputs vignette for more details.
It is now easier to format the borders for specific cells. See the “Formatting cell borders for specific cells” section of the Styling vignette for more details.
Resolved error “Error in columnValues[r - rowOffset] <- v : replacement has length zero” that sometimes occurred when executing bt$asDataFrame().
This release includes one small bug fix: Tables exported to an Excel file would result in blank cells in the Excel worksheet for table cells which had a formatted value but no raw value (i.e. a raw value of NULL). This can occur when exporting pivot tables from the pivottabler package for the row/column headings of totals and for row/column headings when multiple calculations are specified in the pivot table.
The bt$writeToExcelWorksheet() function has new parameter useFormattedValueIfRawValueIsNull which has a default value of TRUE to automatically use the formatted value if the raw value is NULL.
If required, the previous behaviour can be restored by specifying useFormattedValueIfRawValueIsNull=FALSE.
This release includes three breaking changes and numerous small enhancements across various parts of the package.
Argument order changes
The order of the arguments for functions qtbl(), qhtbl() and tbl$addData() has changed. Users relying on the order of arguments may need to update their code. All existing arguments have retained the same name - so users calling these functions using the argument names will be unaffected.
Change of default behaviour in tbl$findCells()
Previously the rowNumbers and columnNumbers arguments of tbl$findCells() were applied in combination e.g. specifying rowNumbers=2:3 and columnNumbers=5:6 previously matched only those cells satisfying both the rowNumbers criteria AND the columnNumbers criteria, which is cells (2, 5), (2, 6), (3, 5) and (3, 6) - and not for example (2, 4).
From v1.0.0 of the package, the rowNumbers and columnNumbers arguments are by default applied independently, e.g. specifying rowNumbers=2:3 and columnNumbers=5:6 will match all cells in rows 2 and 3 and all cells in columns 5 and 6, i.e. cells must match either the rowNumbers criteria OR the columnNumbers criteria.
The previous behaviour can be restored using the tbl$findCells() argument rowColumnMatchMode="combinations".
This change makes the behaviour of tbl$getCells() and tbl$findCells() consistent. It also makes the behaviour consistent with the same functions in the pivottabler package.
stringsAsFactors in R 4.0.x and 4.1.x
From R 4.1.0, the default value of the stringsAsFactors argument in tbl$asDataFrame() changes to FALSE due to the deprecation of default.stringsAsFactors(). When the package is used on versions of R < 4.1.0, the package behaviour is unchanged. When the package used on R 4.0.x versions, a warning message is displayed about the change in future behaviour.
basictabler has been re-written to use the R6 documentation capabilities in roxygen2. As a result the documentation is now more detailed than in previous versions, e.g. arguments in object method calls are now properly documented. Nonetheless, the easiest way to learn the package is using the vignettes.qtbl(), qhtbl() and tbl$addData() functions gain additional parameters numberOfColumnsAsRowHeaders and columnCellTypes that provide additional options for specifying cell types when creating tables from data frames.tbl$mergecells() method gains new parameters rowNumbers and columnNumbers to allow vectors to be used to specify the range of cells to be merged.pt$setStyling() gains new integer/numeric vector arguments rowNumbers and/or columnNumbers to constrain the cells styling is applied to. It is now also possible to specify only a set of row numbers and then all cells in those rows will be styled (and similarly for column numbers). Previously, if only row numbers or only column numbers were specified, then no cells would be styled. Users who require the old logic can specify the argument compatibility=list(legacySetStylingRowColumnNumbers=TRUE) when calling PivotTable$new().pt$setStyling() also gains new arguments cellType and visible to allow these cell properties to be easily specified for ranges of cells. See the styling vignette for more details.pt$mapStyling() simplifies applying styling to cells based on cell value, e.g. banding by value into different colours or colour gradients. See the “Styling” vignette for details plus the “Finding and Formatting” vignette for an example.tbl$getCells() gains a new excludeEmptyCells argument making it easier to exclude cells containing no values. See the “Finding and Formatting” vignette for details.tbl$getCells() also gains a new matchMode argument making it easier to retrieve cells based on combinations of row and column criteria. See the “Finding and Formatting” vignette for details.pt$findCells() gain new arguments rowNumbers, columnNumbers, cellCoordinates, cells and rowColumnMatchMode to restrict the cell search based on combinations of row, column and cell criteria. See the “Finding and Formatting” vignette for details.pt$findCells() also gains new argument valueRanges to enable more granular logic to be specified when matching cell values. See the “Finding and Formatting” vignette for details.tbl$allCells provides a simple way to retrieve a list of all cells in the table.calcFuncArgs argument. See the documentation of the BasicTable$addData(), BasicTable$addMatrix(), TableCells$setRow() and TableCells$setColumn() functions for details.This is a maintenance release that fixes a couple of compatibility issues around the new default of stringsAsFactors=FALSE in data.frame() in the upcoming R 4.0.0 release.
This release includes two small potentially breaking changes to the HTML generated by the package and one bug fix.
Changes to table header cells in HTML
When generating HTML, previous versions of the package rendered all cells using the html td element. More correctly, header cells should be rendered using the th element.
This behaviour also causes compatibility issues with the pivottabler package, which already renders header cells using th - i.e. pivot tables converted to basic tables were rendered differently by basictabler compared to pivottabler.
Starting from this version of basictabler, header cells are rendered as th elements. In most cases, this will make no difference to the visual appearance of the table, however it may cause issues for users who require the previous behaviour. The previous behaviour is still available by specifying compatibility=list(headerCellsAsTD=TRUE) as an argument when creating the table, either in BasicTable$new() or one of the quick table functions such as qtbl().
Originally reported by @rickwargo (thanks!).
Changes to rowspan and colspan attributes in HTML
When generating HTML, v0.2.0 would always generate rowspan and colspan attributes for merged table cells, even if the number of rows or columns being spanned was only one. Starting with v0.3.0, rowspan and colspan attributes are only generated where the number of rows or columns being spanned is greater than one. This should make no difference to the visual appearance of the table, however it may cause issues for users who require the previous behaviour. The previous behaviour is still available by specifying compatibility=list(explicitHeaderSpansOfOne=TRUE) as an argument when creating the table, either in BasicTable$new() or one of the quick table functions such as qtbl().
Calling tbl$setStyling() on the same cell multiple times now succeeds (previously failed with error). Originally reported by @palatinuse (thanks!).
This release includes:
The default value of the specifyCellsAsList argument in the tbl$getCells() function has been changed to TRUE (previously FALSE) since this argument usage is more intuitive and is consistent with the pt$getCells() function in the pivottabler package.
tbl$setStyling() function. See the “Styling” vignette and the “Finding and Formatting” vignette for more details and examples.qtbl() and qhtbl() functions is now possible. See the “Introduction” vignette for a list of parameters for these functions. See the “Styling” vignette for more examples.Tiny change to correct the index entry of the second vignette.
