matrix coercion, logical -> character
Anyone know whether this is intentional, and by which rationale? (R-devel on RedHat, but hardly new)
l <- data.frame(a=rpois(10,1)>0,b=rpois(10,1)>0) apply(l,1,which)
Error in FUN(newX[, i], ...) : argument to "which" is not logical
lapply(l,mode)
$a [1] "logical" $b [1] "logical"
mode(as.matrix(l))
[1] "character"
