I was surprised this morning, that it seems as though the min() function
does not work as *I* anticipated when given vector arguments.
For example:
a <- 1:10
b <- c(rep(1, times=5), rep(10, times=5))
Result:
> min(a,b)
1
What I actually wanted was a term by term minimum, i.e.:
ifelse(a<=b, a, b)
1 1 1 1 1 6 7 8 9 10
Am I losing much in terms of computation power if I use the ifelse?
I'm a little worried, because in implementation my vectors are quite long,
and I will be computing the min of many of them, min(a,b,c,d,e,f) where a
through f are all vectors of the same length.
Any insight that can be provided is much appreciated.
