You need to specify the order of the levels explicitly (to override
the default). Here is how to do it for one, you can similarly do the
other:
> levels(df$Offset)
[1] "T" "U" "V" "Y" "Z" "A" "B" "C" "D" "E" "F" "G" "H"
> df$Offset <- factor(df$Offset,
+ levels = c("T", "U", "V", "Y", "Z", "A",
+ "B", "C", "D", "E", "F", "G", "H"))
> levels(df$Offset)
[1] "T" "U" "V" "Y" "Z" "A" "B" "C" "D" "E" "F" "G" "H"
Once you make these changes, your original call should work as desired.
