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
