gridpattern: 'grid' Pattern Grobs

Description

Provides 'grid' grobs that fill in a user-defined area with various patterns. Includes enhanced versions of the geometric and image-based patterns originally contained in the 'ggpattern' package as well as original 'pch', 'polygon_tiling', 'regular_polygon', 'rose', 'text', 'wave', and 'weave' patterns plus support for custom user-defined patterns.

Package options

The following gridpattern options may be set globally via base::options():

ggpattern_array_funcs

Set custom “array” pattern functions.

ggpattern_geometry_funcs

Set custom “geometry” pattern functions.

ggpattern_res

Set custom raster image resolution (pixels per inch) for certain patterns.

ggpattern_use_R4.1_clipping

If TRUE use the grid clipping path feature introduced in R v4.1.0. If FALSE do a rasterGrob approximation of the clipped pattern. If NULL try to guess an appropriate choice.

ggpattern_use_R4.1_features

If TRUE sets the default for all the other ⁠ggpattern_use_R4.1_*⁠ options arguments to TRUE. If FALSE sets them to FALSE.

ggpattern_use_R4.1_gradients

If TRUE use the grid gradient feature introduced in R v4.1.0. If FALSE do a rasterGrob approximation of the gradient pattern. If NULL try to guess an appropriate choice.

ggpattern_use_R4.1_masks

If TRUE use the grid mask feature introduced in R v4.1.0. If FALSE do a rasterGrob approximation of the masked pattern. If NULL try to guess an appropriate choice.

ggpattern_use_R4.1_patterns

If TRUE use the grid pattern feature introduced in R v4.1.0. Currently only used by a couple of examples.

Note to use the R v4.1.0 features one needs R be (at least) version 4.1 and not all graphic devices support any/all these features. See https://www.stat.auckland.ac.nz/~paul/Reports/GraphicsEngine/definitions/definitions.html for more information on these features.
