Hi, I'm using data.frame(..., check.names=FALSE), because I want to create a data frame with duplicated column names (in the real life you can get such data frame as the result of an SQL query):
> df <- data.frame(aa=1:5, aa=9:5, check.names=FALSE) > df aa aa 1 1 9 2 2 8 3 3 7 4 4 6 5 5 5 Why is [.data.frame changing my column names? > df[1:3, ] aa aa.1 1 1 9 2 2 8 3 3 7 How can this be avoided? Thanks! H. ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
