Dropping columns from data frame
...e.g. why doesn't the column formerly-known-as-4 become 3 after column 1 is dropped: doesn't vector removal from a df/list invoke a loop in C?). Can I delete a named list of columns, which are examples 4 and 5 and which generate the "unary error' mesages, without resorting to "orig.df$num1.10 <- NULL"? Thanks! orig.df <- data.frame(cbind( 1:10 ,11:20 ,letters[1:10] ,letters[11:20] ,LETTERS[1:10] ,LETTERS[11:20] )) names(orig.df) <- c( 'num1.10' ,'num11.20' ,'lc1.10' ,'lc11.20' ,'uc1.10' ,'uc11.20' )...
