In R functions are "things" but they are not "strings" and cannot be  
executed by just asserting a character vector element. If you want to  
construct a 'call' from a acharacter, you can bridge that divide with  
do.call:

?do.call
fn <- paste("d", "gamma", sep="")
do.call(fn, list(1:10, shape=1) )

0.00673794700
  [6] 0.00247875218 0.00091188197 0.00033546263 0.00012340980
