Hello,
I have data in a dataframe with 139104 rows which is multiple of 96x1449. i
have a phenotype file which contains the phenotype information for the 96
samples. the snp name is repeated 1449X96 samples. I haveto merge the two
dataframes based on sid and sen. this is how my two dataframes look like
dat<-data.frame(snpname=rep(letters[1:12],12),sid=rep(1:12,each=12),
genotype=rep(c('aa','ab','bb'), 12))
pheno<-data.frame(sen=1:12,disease=rep(c('N','Y'),6), wellid=1:12)
I have to merge or add the disease column and 3 other columns to the data
file. I am unable to use merge in R. I have searched google, i guess i am
not hitting the correct terms to get the answer. I would appreciate any
input on this issue. thanks
sharad
