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

a2:11,12,13,14,15,16,17,18,19,20

a3:21,22,23,24,25,26,27,28,29,30

a4:31,32,33,34,35,36,37,38,39,40

 

 

The max value in the four columns (a1,a2,a3,a4) is 40. The new data.frame is

 

ID:10

A1:10

A2:20

A3:30

A4 :40

 

Thanks

 

Ale
