[R] value of variable in ls()

[Christian Hoffmann]

This may seem trivial:

ls() gives me names of variables as a character vector. How can I print 
the values 'behind' those character values:

ls()
 > "a"
 > a
[1] 5

How can I do e.g. print("unknown"(ls())) and get the variable values in 
my current environment?
