    sub = names(x$tab), abline = TRUE, ...)

Arguments

x

an object of class pca

xax

the column number for the used axis

which.var

the numbers of the kept columns for the analysis, otherwise all columns

mfrow

a vector of the form "c(nr,nc)", otherwise computed by a special own function n2mfrow

csub

a character size for sub-titles, used with par("cex")*csub

Examples

data(deug)
dd1 <- dudi.pca(deug$tab, scan = FALSE)
score(dd1, csub = 3)
 
# The correlations are :
dd1$co[,1]
# [1] 0.7925 0.6532 0.7410 0.5287 0.5539 0.7416 0.3336 0.2755 0.4172
