The package "PSTricks" implements layers in the R language above the PSTricks macro package for LaTeX (and TeX) by providing wrapper functions for many of the macros.

Higher-level functions are also available to produce plots, including some "ggplot2"-like functions with a similar, but not completely identical, functionality.

When using these functions, an R object is created with the associated LateX lines, which is by default automatically converted to a PDF document.
