Hi I''m building a small library to use in my Rails app which interacts with a 3rd party API. It fetches artists and tracks. So I have: lib/my_lib.rb lib/my_lib/artist.rb lib/my_lib/track.rb To get an artist I do artist = MyLib::Artist.find("Oasis") Which returns an instance of Artist if it finds (via 3rd party API) it or nil otherwise. Then I can call artist.tracks which

Gracias, Carlos. Habia pensado en algo similar usando sapply(): sapply(seq(1, ncol(vtmp), by = 2), function(i) c(rbind(as.character(vtmp[, i]), as.character(vtmp[, i+1])))) Dependiendo de la dimension de los datos, quizas mapply() sea mas eficiente que sapply().

Hey everybody I''m sorry, I know that this question seems to arise every few moments, but I think in my case it''s a bit special (but doesn''t everybody?).
