...my species (Especie) are listed, in which order. I found that they are not listed in alphabetical order (using rudimentary data management skills). Is there a way to reorder them in alphabetical order? and if not, how do I see the order of my 277 species? Thank you, -- --- Lic.

Dear list, I'm working with a large data set, where I grouped several species in one group (guild). Then I reshaped my data as shown below. Now, I just want to have "Rep" only as 1 or 0. I'm not being able to change the values of rep>=1 to 1... tried many things and I'm not being successful! > melting=melt(occ.data,id.var=c("guild", "Site",

List, I want to reshape my data, but I'm not sure how to do it... it might be a simple task, but don't know which package does this. "occ.data" (see below) is how my original data are arranged, and I know that with melt() I can reshape it like "y" (see below). However, I just want to build a matrix like the "y" matrix, but with only 2 dimensions. Something

I've been trying to reshape this database but haven't succeed at it. I tried using loops but can't get it right. I just want to reshape my database from this matrix, to the one below, with only one column of data.
