[R] position of an element in a vector

[Jason Bond]

Hello.  Sorry for the elementary post.  I've looked through the 
documentation, but can't seem to find a function which allows one to 
extract the position of an element within a list...for example the position 
of the element 4 in the vector c(1,2,4,3,6) is 3.  Thanks much for any help.
