Subject: [R] assign to an element of a vector


I am trying to find a way to assign values to elements of a vector that will
be defined by a user. So I don't have the name of the vector and cannot hard
code the assignment in advance. In the example below I have to get() the
vector using its name. When I try to assign to an element I get an error:

> a <- c(1,2,3)
> get('a')[1] <- 0
Error: Target of assignment expands to non-language object

Any suggestions?
