r-cran-sys - 3.4.2-1 main

Drop-in replacements for the base system2() function with fine control
and consistent behavior across platforms. Supports clean interruption,
timeout, background tasks, and streaming STDIN / STDOUT / STDERR over
binary or text connections. Arguments on Windows automatically get
encoded and quoted to work on different locales. On Unix platforms the
package also provides functions for evaluating expressions inside a
temporary fork. Such evaluations have no side effects on the main R
process, and support reliable interrupts and timeouts. This provides the
basis for a sandboxing mechanism.
