I find it
difficult to give a better advice considering the little information you
provided about your problem.
If that doesn't help, perhaps you could send a simple and reproducable
example of what you want to do.

Dear R-help,
As a generalization, is it more efficient to use a single method to
selectively transform items in a matrix? Preferably whole-vector, yes;
but if one of the column vectors compels the use of a "for loop", is it
then faster to do all of the transformations for the matrix via that
"for loop", rather than use a mixture of methods on a column-wise basis?
TIA
