New Features in the R Graphics Engine

Support for gradient fills, pattern fills, clipping paths and masks has been added to the R graphics engine (in the development version of R, which will probably become R version 4.1.0). An R-level interface for these new features has been added to the ‘grid’ graphics package. library(grid) For example, the following code fills a circle with a linear gradient. grid.circle(gp=gpar(col=NA, fill=linearGradient())) The next code fills a rectangle with a radial gradient.
