Hi
X <- data.table(a=rep(1:3,1:3),b=31:36,c=7:12)
X
setnames(X, 2, "a" ) ## two column named "a" now
X
X[,2:=200L, with=FALSE ] # Change the entries of column 2
X[,2, with=FALSE ] # Instead of changing
column 2, the code
appears to have done a look up on the column names and picked the first
match
X
Can anybody tell me how to change column 2 in this example when I have
duplicate column names?
Thanks
Sean
