paintr 0.0.1 (2026-08-06)

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

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>.

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.

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.
