What does the warning mean? What sort of problem?
model.data <- merge(Y1, Y2, all = FALSE, suffixes = c(".Y1", ".Y2"))
Warning message:
In merge.data.table(Y1, Y2, all = FALSE, suffixes = c(".Y1", ".Y2")) :
There was a problem re-suffixing the merged data.table. The merge was
succesful, but the default column naming has been used (ie. suffixes
were set to c('', '.1').
It doesn't seem to matter what value I use for suffixes=
