The "c" function creates vectors. Rows of data frames are data frames, not vectors. new_row <- data.frame( Prod_name = "Day_name", `Date 1`=1, `Date 2`=2,`Date 3`=3 ) data_may <- rbind( new_row, data_may ) Furthermore, data frames are NOT spreadsheets. "Day_num" looks suspiciously UNlike a

Hi Bailey, Treat it as a guess, but try this: for (i in c(1:3)){ y<-mydata[,i] x <- mblm(y ~ Year, mydata, repeated = FALSE) print(x) } I'm not sure that you can mix indexed columns with column names. Also, Year is column 4, no? Jim On Sun, Sep 4, 2016 at 11:43 AM, Bailey Hewitt
