[R] Removing a list of Objects

[Gabor Csardi]

I assumed that 'a' is a character vector. In your case it seams that 'a'
is a list with a single element, a character vector. I've no idea 
why you would want to use such a data structure for this, but if you
do want to, then the command is 

rm(a[[1]])

See also ?rm and maybe also 'Introduction to R' could be useful.
