Turns out my column and row names were too long to fit in the console and when I widened the window the table didn't automatically adjust and widen as well. I had to widen the console first and then retype the same command so it fit. Silly mistake. I usually keep the console pretty narrow on my lap

You could do something like the following > rowsToShiftLeft <- c(2,4,5) # 4, not the 3 that was in the original post > mat <- as.matrix(df_start) > mat[rowsToShiftLeft, 1:3] <- mat[rowsToShiftLeft, 2:4] > result <- data.frame(mat[, 1:3], stringsAsFactors=FALSE) > str(result) 'data.frame
