Hi Michael, Thank you so much for the help Michael! When I put my package 'PKG2' (on which PKG1 is depending on) in the regular place, perhaps a place R CMD check won't look at, then when I try to build PKG1, they will say PKG2 required but not found, so I have to put it under a directory R looks at, just the paths under '.libPaths()'. I read through the manual (the 7th section entitled "tools"of "R internals"), and they suggest changing check.Environ under ~/.R, so I have tried to put check.Environ "~/.R", "~/" is my home directory which is just the path shown after typing cd &&pwd. But It doesn't work, so I thought "~/" might be something else. Thank you so much for the help, I really appreciate that! Yours, Xuan

On my Mac it is "/Users/mweylandt" and I imagine you'd get something similar on all Linux and BSD systems -- one easy way to see where it is: go to your terminal and type "cd && pwd" which will print it out. No idea what the parallel on Windows is: possibly something under C:/Documents and Settings but it's been so long since I've had the misfortune of doing serious work on Windows, I can't remember. Incidentally, is there a reason you can't put your package in the "regular" place? Finally, see the manuals that Bert, Josh, and I have pointed you to: they are much more authoritative on these matters than any of us.
