Hello, I'm fairly new to R, and despite spending quite some time exploring, testing, and looking for answers, I still have a couple of questions remaining...
The first one is about creating a dataframe using a list of the variable names . I get this output file from a database: BOB <- c('A/A', 'C/C', '15/27') MARY <- c('A/A', NA, '13/12') JOHN <- c('A/A', 'C/A', '154/35') CLIFF <- c('A/C', 'C/C', '15/12') PAM <- c('A/C', 'C/A', '13/12') sampleList <- c("BOB", "MARY", "JOHN", "CLIFF", "PAM") polyList <- c("rs123", "rs124", "rs555") to create a dataframe with the data I use: data.raw <- data.frame(BOB, MARY, JOHN, CLIFF, PAM, row.names=polyList) which works fine, but when there are several hundreds samples... well, you guess my problem. I'd like to create the dataframe using the list of the variables, contained in sampleList - i.e. something like data.frame(function(sampleList), row.names=polyList) Is that possible, and if yes, how? Thanks in advance, Stephane
