[R] PCA factominer package, question about changing labels in individuals factor map

I am looking to do a PCA with the factominer package on a dataset of mine,
named dat. The individuals in my dataset have character names, represented
in the first column of my dataset, but since they aren't quantitative I
can't include that column in my PCA analysis. Leading to the command >
res.pca = PCA(dat[,3:8], scale.unit=TRUE, ncp=5, graph=T)

This is all well and good, except when my individuals factor map shows up,
each data point is labeled as a number and not as their actual character

 How do I go about getting the map to display the character names? If I
include the column with the names I get an error because it's not
quantitative. I know it can be done because I've seen it on the decathlon
dataset, I just don't know what they're doing differently to get those
character names on the map.
