Thanks for your reply, Duncan. I hoped for an auutomatic way without
manually having to load the packages to exist ... Perhaps this time this
is not the case.
Cheers

Dear list members,
I frequently program small scripts and wrap them into functions to be
able to check them with checkUsage. In case these functions (loaded via
source or copy pasted to the R console) use functions from other
packages, I get this error:
no visible global function definition for ‘xxxxxxx’
For example:
test = function() {
require(plotrix)
color.legend()
}
library(codetools)
checkUsage(test)
Can I tell codetools somehow where to look for these functions without
building a full blown package?
Sure, just attach the other package. For example:
> f <- function() plot3d(1,1,1)
> library(codetools)
> checkUsage(f)
<anonymous>: no visible global function definition for ‘plot3d’
> library(rgl)
> checkUsage(f)
