* fixed part of the pMincApply code that produced a warning. A vector was checked for equality with the empty string, but if the vector contains multiple elements, the condition returns multiple booleans. In R the first boolean is then evaluated as the answer for the if condition. This is what the warning was about. Only in extreme cases (were you pass the vector c("","car",...) for instance) to pMincApply would the wrong choice be made.
