Package grDevices has a function cm() to convert from inches to centimeters.
Its definition is:
cm<- function(x) 2.54*x
As far as I can tell, the function is not used anywhere in the R sources (I grepped for "cm(",
"cm)" and ", cm".) I did not check for all packages on CRAN, though.
I found it easier to remember cm() rather than 2.54.
By the way, before deprecating (rather than at once removing) a
function: have you also grepped through all CRAN and BioC packages?
And have you grepped for "\"cm\"", "'cm'" and other occurrences? cm may
be called in a call(), do.call() or other construct, hence the real test
is to remove the cm function, rebuild R and run the checks and run
checks on all at least all 3000 packages from CRAN + BioC.
Best wishes,

May I propose to remove this apparently useless function from the sources?
[I stubbled upon this function because my package actuar also has a cm()
function that masks the one from grDevices.]
