Dear R members,
Sorry for this question. I have a dataframe (please see the example) and i
should do the following transformation:
DF
a b c d e f g h i n
14 24 rcvf AG 5 2 1 0 2 1
58 42 grde AC 2 5 0 5 1 0
I should transforme my DF like :
a b c d e f g h i n
14 24 rcvf A G 0 0 G G A G G G G G A A
58 42 grde A C C C 0 0 A A 0 0 A C A A
i.e: when DF[i,j]==5 => DF[i,j] <- 0 0
When DF[i,j] == k (!=0) i should look to d column to do the
transormation
DF is 200000 * 10000 so i cant use loops.
Thanks for your help,
Claire
