[R] select one row from data-frame by name, indirectly (as string)
Hello, say I have a dataframe x and it contains rows like ch_01, ch_02 and so on. How can I select those channels iundirectly, by name? I tried to select the data with get() but get() seems only to work on simple variables? Or how to do it? I need something like that: name1 - ch_01 name2 - ch_02 selected - function( x, name1) Any ideas? __ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.

Provide your console session and someone can tell you. Failing that, you are asking us to read your mind.
