R devel - May 2010 - R CMD check

Hi,
I have been finding clues on the internet to understand the reason for this
warning.
The package i have made, builds, installs and works well, except for this
warning when I check it:

When I run:
R CMD check mypack_1.0.tar.gz
... ... .. ..
* checking R code for possible problems ... NOTE
Found possibly global 'T' or 'F' in the following functions:
  HWE procRef readMartFile readPhase2File
.. ... .. 



I have several other functions in the package, but the warning is for this
subset.

I am trying to find a common thing within this subset, and cant figure out one
to go after it.

Thanks a lot for the help.


Regards,
Sahil Seth

Look for spots where you sloppily have used, say, na.rm=T instead of
na.rm=TRUE.

This kind of construction will break if something redefines T/F
globally, hence the warning. (The code checker heuristics first looks a
local definition of T or F, in which case things are fine, or at least
not wrong for this particular reason.)
