Question

I am using match for getting if an element is in a list. For example my list is:

  c("a","b","h","e"...) and so on

if I want to see if element h is in the list I am using match in this way:

  if ("h" %in% v){do something}

How I can get the position of where it finds the element in the list?
Thanks

Answer 1

If you want to know the position use which

l <- c("a","b","h","e")
which(l=='h') 
[1] 3   # It'll give you the position, 'h' is the third element of 'l'

Note that l is a vector, not a list as you mentioned.
