Why does the naming have to be done inside the cbind()? How about
> dataTest <- data.frame(col1 = c(1,2,3)) > new.data <- c(1,2) > name <- "test" > length(new.data) <- nrow(dataTest) > newDataTest <- cbind(dataTest, new.data) > names(newDataTest)[[ncol(newDataTest)]] <- name > newDataTest col1 test 1 1 1 2 2 2 3 3 NA ? -----Original Message----- From: r-help-boun...@r-project.org [mailto:r-help-boun...@r-project.org] On Behalf Of Ralf B Sent: Friday, 25 June 2010 3:48 PM To: r-help@r-project.org Subject: [R] Assigning variable value as name to cbind column Hi all, I have this (non-working) script: dataTest <- data.frame(col1=c(1,2,3)) new.data <- c(1,2) name <- "test" n.row <- dim(dataTest)[1] length(new.data) <- n.row names(new.data) <- name cbind(dataTest, name=new.data) print(dataTest) and would like to bind the new column 'new.data' to 'dataTest' by using the value of the variable 'name' as the column name. The end result should look like this: col1 test 1 1 1 2 2 2 3 3 NA The best I got was that 'name' became the column name but never the actual value of 'name'. How can i do that? (This is actually a function that runs many time -- this means a manual workaround is not feasible).
