Here is the code which reproduces the issue:

r$> m <- pca(as.data.frame(people))                                                                                           

r$> rownames(m$res$cal$scores)                                                                                                
NULL

r$> m <- pca(people)                                                                                                          

r$> rownames(m$res$cal$scores)                                                                                                
 [1] "Lars"       "Peter"      "Rasmus"     "Lene"       "Mette"      "Gitte"      "Jens"       "Erik"       "Lotte"     
[10] "Heidi"      "Kaj"        "Gerda"      "Anne"       "Britta"     "Magnus"     "Casper"     "Luka"       "Federico"  
[19] "Dona"       "Fabrizia"   "Lisa"       "Benito"     "Franko"     "Alessandro" "Leonora"    "Giuliana"   "Giovanni"

In PLS everything works fine.
