Details

Note, the current directory is always searched at the beginning. This provides an easy way to override other files in the search path. If paths is NULL, then a set of default paths are searched. The default search path is consituted of:

1. "."

2. getOption("AFFX_APD_PATH")

3. Sys.getenv("AFFX_APD_PATH")

One of the easiest ways to set system variables for R is to set them in an .Renviron file, see Startup for more details.

Value
