Oh, sorry, I just realized that I messed up the indicing. Here is the correct way:
> z <- data.frame(a=1:3,b = letters[1:3]) > i <- seq_len(nrow(z)) > z<-z[rep(i,e=2),] > z[2*i, ] <- matrix(NA, nr=nrow(z),nc=ncol(z)) > z Still doubt that this is a good idea, though. -- Bert Bert Gunter "The trouble with having an open mind is that people keep coming along and sticking things into it." -- Opus (aka Berkeley Breathed in his "Bloom County" comic strip ) On Sun, Apr 24, 2016 at 8:53 AM, Bert Gunter <bgunter.4...@gmail.com> wrote: > Well, something like this would work (there may be slicker solutions): > >> z <- data.frame(a=1:3,b = letters[1:3]) >> i <- seq_len(nrow(z)) *2 >> z <-rbind(z,z) >> z[i, ] <- matrix(NA, nr=nrow(z),nc=ncol(z)) >> z > a b > 1 1 a > 2 NA <NA> > 3 3 c > 4 NA <NA> > 5 2 b > 6 NA <NA> > > But I agree with you that there is probably a way to handle the > underlying issues that does not require this kind of artifice. > > Cheers, > Bert > > > > Bert Gunter > > "The trouble with having an open mind is that people keep coming along > and sticking things into it." > -- Opus (aka Berkeley Breathed in his "Bloom County" comic strip ) > > > On Sun, Apr 24, 2016 at 8:21 AM, Ulrik Stervbo <ulrik.ster...@gmail.com> > wrote: >> Hi Saba, >> >> I don't know how to do what you want and I also cannot see why. >> >> If you describe what you hope to achieve there might be a different >> solution. >> >> Best wishes >> Ulrik >> >> Saba Sehrish via R-help <r-help@r-project.org> schrieb am So., 24.
