Well, its mentioned in the function itself by library(xxx) or
require(xxx). Well, most probably codetools is more aimed towards
checking packages in whcih case such information is in the depends
section of the package declaration.

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.
That doesn't make sense. How could checkUsage possibly know what
packages you plan to attach if you don't tell it?

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)
