Hi all, I have a huge data set. All I want to do is to change the column names of the it. So if I use read.table, I can read the data in and change colnames and then write back, such as,
t <- read.table("a.txt", header = T, sep = "\t") colnames(t) colnames(t) <- c("....) # new column names write.table(t, "a.txt", quote = F, sep = "\t", row.names = F, col.names = T) My question is that is there a better to do this without reading in and write out data entirely? Thanks.
