Hi Beatriz,
I'll guess that you have a number of files with names like this:
Samples_1.txt
Samples_2.txt
...
Each one can be read with a function like read.table and will return a
data frame with default names (V1, V2, ...). You then want to extract
the first element (column) of the data frame. I

In my environment I have a data frame called Samples_1.txt.
From this data frame I need to get variable V1. My code doesn't work. Thanks!
sprintf("Samples_%s.txt", 1)$V1
Note: I need to do it in this way because I have the code into a for loop.
