...nd a fairly advanced Stata-user, I guess part of my problem is that my mindset (and probably my language as well) is wrong. Anyway, I have what I guess is a rather simple problem, that I now without success spent days trying to solve. I have a bunch of datasets imported from Stata that is labelled aa_2000 aa_2001 aa_2002, etc. Each dataset is imported as a matrix, and consists of one column only. The columns consists of integer numbers. I need to convert the data to vectors, which I found several ways to do. I use, for example: aa_2000 <- as.numeric(aa_2000[,1]) However, when trying to automate t...

...thing we Stata-users do, I just jokingly pointed it out). Anyway, I'm really happy that you try to teach me some R-manners. Since I still get questions about what the h**k I mean by my strange question, I sort it out with an example: I had a number of matrices, named in a consecutive manner: aa_2000 <- as.matrix(read.csv(text="1,0,1,1,0,0,0,0,0,0,1,0,0", header=FALSE)) aa_2001 <- as.matrix(read.csv( text="0,0,0,1,0,1,1,0,0,0,0,1,0,0", header=FALSE)) aa_2002 <- as.matrix(read.csv( text="1,0,0,0,0,0,0,0,1,0,0,0,0,1,0,0", header=FALSE)) I needed them to be...
