[R] simplify source code

[Christof Kluß]

Hi

now I'd like to do

for (colname in c('ColName1','ColName2','ColName3')) {		
     dat <- measurements$colname

But that does not work, though I can write

measurements$"C1" (same as measurements$C1)
(but different to measurements["C1"]!)

Can you give me a hint?

greetings
Christof
