Dynamically build variable names
I'm trying to dynamically build variable names to use on a list. Let's say I have a list like this one:
l <- list(V1_1=c(1,2,3), V1_2=c('One','Two','Three'))
And I succesfully build my variable name like this:
paste('l$', 'V1_1', sep='')
Why can't I just run a mean call with the pasted variable name?
mean(paste('l$', 'V1_1', sep=''))
So, my question...
