I want to find the position of the values that are not zero, for example in row one I want to know how I get 3400 that is in column s8, for the second row I want to find the position of the first element 660, and for the third row I want to know the position of s8 4679. and so on for each row.

        s1      s2      s3      s4      s5      s6       s7      s8      s9     s10     s11

  • `max_col <- names(df)[max.col(df, ties.method = 'first')]` – Ronak Shah Nov 28 '20 at 02:18
  • i am using this, cont <- function (x) { m<-which(x!=0)[[1]] print(m) } but when I use it to my data frame I get an error, it gives me the result but in the end I get an error and it does not save the result, I do not know if my function may be wrong. – jans castellon Nov 28 '20 at 03:16
