Hello All,
I have a list of dataframes, and I need to subset it by keeping only those
dataframes in the list that meet a certain criterion. Specifically, I need
to generate a second list which only includes those dataframes whose number
of rows is> 1.
Could someone suggest how to do this? I have come close to what I need with
loops and such, but there must be a less clumsy way...
L.new <- L[tapply(L,nrow) > 1]
cheers,
Rolf Turner
