[R] simple for loop

"i" just contains a string.  What you want is the object with that name,
which is what get() gives you.  Do read the help page for get().

this works so far, but could you please give my a hint what I did wrong?
what does the get() do ?

I was struggeling inside some other for loops, and it seems that there
was another get() missing.
So do I have to use the get() always inside a loop in order to "get" the
correct i-values pasted in ?

Thank you
