My guess is that it has something to do with the class of the
variables. Perhaps you could provide a small sample dataframe? Also
you might try running str() on your data frame and seeing if the
results are what you would expect. As a side note, it is not
necessary to make an anonymous function here, as you are allowed to
pass arguments to the function applied.
apply(canc[,vec],1, min, na.rm=TRUE)
