[R] dir.create only gives first character of name when warning

[Keith Ponting]

This is not a major issue, but is there any way to get the full
directory name out when dir.create issues a warning?
I am running R 2.8.0 patched on Windows Vista - full details below.

With the following code:
  dir.create("test")
  obscure<-"test"
  dir.create(obscure)
I get the warning message:
  In dir.create(obscure) : 't' already exists
