paintr 0.0.1

Initial CRAN submission. The package was previously developed as drawr.

Breaking changes

• Numbers draw at three significant figures by default, tunable with sigfig.
• Large matrices, vectors, and data frames elide their middle past a size cap, overridable with max_rows, max_cols, or show_all = TRUE.
• A data frame’s list column shows each element’s type and size, like <int [3]>, instead of a bare <list>.

New features

• paint_list() and gpaint_list() draw a list, each element a column and its values the rows, which is the picture a data frame makes once its columns share a length. show_indices = "cell" labels cells with the [[j]][i] accessor, and summarise = TRUE collapses each element to a single cell.
• Named vectors, matrix dimnames(), and data-frame row names are drawn as labels, toggled with show_names, show_dimnames, and show_rownames.
• paint_data_frame() and gpaint_data_frame() (aliases paint_df() and gpaint_df()) draw a data frame with a per-column type band, controlled by show_names and show_types.
• gpaint_vector() completes the paint_*() and gpaint_*() pairing for every structure.
• paint_size() returns the device size a structure needs to stay legible, in inches, centimetres, or pixels.
• Cell text is fitted to the available space so it no longer overflows, with fontsize and family to override.
• Insignificant trailing digits are greyed rather than dropped, tunable with subtle_digits.
• Long strings are truncated to max_chars with an ellipsis.

Bug fixes

• Character matrices and vectors render their values instead of a red Unknown.
• highlight_data() and the highlight_rows(), highlight_columns(), and highlight_locations() helpers no longer error on character vectors, logical vectors, or data frames, and accept row and column names.
• Graphics parameters are restored after paint_matrix() and paint_vector().
• paint_matrix()’s type error no longer claims the data should be a vector.
