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?

OK, now it works... just using [ and ]  or [[ and ]] works.
I thought have tried it before... why does it workj now and not before?

hmhh


sorry for the traffic

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