ggpairs Change the colum label of factor levels

It is possible to change the column label of factor levels without having to change the values in the data.frame

for example in the following graph can I change the label of Female and Male to F and M respectively without having to change the df?

library(GGally)
data(tips, package = "reshape")
pm <- ggpairs(tips, 1:3, columnLabels = c("Total Bill", "Tip", "Sex"))
pm

tips

After 

pm <- ggpairs(tips, 1:3, columnLabels = c("Total Bill", "Tip", "Sex"))

do this

levels(pm$data$sex)[levels(pm$data$sex) == "Male"] = "M"
levels(pm$data$sex)[levels(pm$data$sex) == "Female"] = "F"

You'll get this plot:

enter image description here

It won't change anything in tips dataset:

head(tips)

 total_bill  tip    sex smoker day   time size
1     16.99 1.01 Female     No Sun Dinner    2
2     10.34 1.66   Male     No Sun Dinner    3
3     21.01 3.50   Male     No Sun Dinner    3
4     23.68 3.31   Male     No Sun Dinner    2
5     24.59 3.61 Female     No Sun Dinner    4
6     25.29 4.71   Male     No Sun Dinner    4
