Or,

> dimnames(p)
[[1]]
[1] "acet"  "chol"  "ino"   "acetp"
> dimnames(p)[[1]]
[1] "acet"  "chol"  "ino"   "acetp"
> dimnames(p)[[1]] <- c("Acetylaspartate Thalamus", "Choline Thalamus", "Acetylaspartate parieoc", "Inositole Thalamus")
> p

which is more easily generalizable when more than one conditioning
variable is involved.
