HI,
If I understand correctly, you could also try:
set.seed(48)
d2 <-
as.data.frame(matrix(sample(c("",letters[1:2]),26*245,replace=TRUE),26,245))
d2[3,] <- ""
names1 <-paste0("V",13:239)
res <- d2[rowSums(d2[,names1]=="") < ncol(d2[,names1]),names1]
A.K.

O-ha, sorry, Luca, I mixed up arguments: it shouldn't be "subset" but
"select".
apply( subset( d2, select = V13:V239), 1, function( x) any( x != ""))
should work.
"Auf Wiederhören!" ;-)

Hello, Luca,
also a happy new year!
It's not quite clear to me what you want to do, but note first that the
":"-operator is a short-cut for seq() with by = 1 (look at ?seq), and that
it usually (!) does not work on columns of data frames. Exception: when
used for the argument subset of functi
