Hi Ale,
perhaps something like this will work for you:
ID <- c(1,2,3,4,5,6,7,8,9,10)
a1 <- c(1,2,3,4,5,6,7,8,9,10)
a2 <- c(11,12,13,14,15,16,17,18,19,20)
a3 <- c(21,22,23,24,25,26,27,28,29,30)
a4<- c(31,32,33,34,35,36,37,38,39,40)
df <- data.frame(cbind(ID, a1, a2, a3, a4))
# get max by row, exc
Dear User,
thank for the attention. I have a data.frame with 5 columns (ex:ID,
a1,a2,a3,a4) and 1000 rows. I wish to find the absolute max value for all
data.frame and save a new data.frame with the row where is that value. Ex:
ID: 1,2,3,4,5,6,7,8,9,10
a1:1,2,3,4,5,6,7,8,9,10
a2:11,12,13,
