Hi Rasmus,
Please see the following commands. The box fails.
> library("FactoMineR")
> mydata <- read.csv('test.csv', header=T,row.names=1)
> res.pca = PCA(mydata, quali.sup=5, graph=F)
> plot(res.pca, choix="ind")
> box(col='black')
Error in box(col = "black") : plot.new has not been called yet
Regards,
Mahmood
