Replace multible data codes in a datafram with names
- by Shabana
I have a problem in replacing codes in a dataframe of 3890 observations.
My dataframe has a character variable df$IJN which contains values from 1 to 27. I would like to replace these with meaningful data as follow
If(1 OR 6 OR 10 OR 14 OR 18 OR 22 OR 26) should be replaced with UL.
If(3 OR 7 OR 11 OR 15 OR 19 OR 23 OR 27) should be replaced with LL.
If(4 OR 8 OR 12 OR 16 OR 20 OR 24) should be replaced with UR.
If(5 OR 9 OR 13 OR 17 OR 21 OR 25) should be replaced with LR.
(U,L,R,and L Refer to Upper, Lower, Right, and Left sites in the order)
I thought of a for() with if() could not manage with it
Also thought of df[which(df=="27")] ="LL" may work one by one not sure!
Any help please. R v3.1 - Windows 7
