[R] Problem accessing functions in package 'roxygen'

[Robert A LaBudde]

Thanks, Uwe. Unfortunately, that doesn't work either:

 > library('roxygen')
Warning message:
package 'roxygen' was built under R version 2.9.1
 > roxygen::trim(' 1234 ')
Error: 'trim' is not an exported object from 'namespace:roxygen'

I ended up using

trim <- function(x) gsub("^[[:space:]]+|[[:space:]]+$", "", x)

instead.
