Subject: [R] execute array of functions
Hi all,
I'm trying to get the min and max of a sequence of number using a
loop
like the folllowing. Can anyone point me to why it doesn't work.
Thanks.
type <- c("min","max")
n <- 1:10
for (a in 1:2) {
print(type[a](n)) }
> n=1:10
> for (a in c(min,max)) {
+ print(a(n)) }
[1] 1
[1] 10
> funs <- c(min,max)
> for (a in funs) {
+ print(a(n)) }
[1] 1
[1] 10

I am not sure why you are trying to use this approach in a loop, but
you need to use the get() function if you want to do this.
type <- c("min","max")
n <- 1:10
for (a in 1:2) {
print(get(type[a])(n))
}
But, why not use min and max on n directly?
Hope this is helpful,
Dan
