Hi, is there any way I can change the column header in a data.frame?

If you data.frame is called df, then names(df) <- c(new names here) You can also do individual names names(df)[1] <- "new name for first column" HTH Jim James W.

Consider the following:
DF <- data.frame(a=1:2, b=3:4)
names(DF) <- letters[1:2]
DF
dimnames(DF)[[2]][2] <- "z"
DF
This example illustrates two different ways to do what I
understood from your question. Answered?
