Arguments

Value

is_r wraps is.R, providing more information on failure. is_r_stable, is_r_patched, is_r_devel, etc., tell you what type of R build you are running. is_architect, is_rstudio and is_revo_r tell you if you are running Architect/StatET, RStudio, or Revolution Analytics' Revolution R build. is_slave_r tells you if you are running a slave instance of R (e.g. when building a package with devtools or using a cluster). The assert_* functions return nothing but throw an error if the corresponding is_* function returns FALSE.
