Hi
I have a little function that takes a vector v and an integer i. I want
to manipulate
v[-i] (to give v.new, say) and
then put (unmanipulated) v[i] back into the appropriate place. For
example,
f <- function(v,i){
v.new <- v[-i]+10
return(c(v.new[1:(i-1)],v[i],v.new[i:length(v.new)]))
}
Take the complement of 'i', and change the values of v in place?
f <- function(v,i){
v[-i] <- v[-i]+10
v
}
Now i can be an integer or a vector of integers or true/falses.
