R help - Aug 2016 - changing x and y ranges in a PCA plot created by library(labdsv)

I want to change x and y ranges in a PCA plot created by library(labdsv).
When I run "plot(o.pca, xlim=c(-2, 3), ylim=c(-2, 4))", nothing will
change. Script is as fallow:



raw<- matrix(c(1,2,2.5,2.5,1,0.5,0,1,2,4,3,1),nrow=6)

colnames(raw)<- c("s1","s2")

rownames(raw)<-
c("r1","r2","r3","r4","r5","r6")

cent<- scale(raw,scale=FALSE)

o.pca <- pca(cent)

plot(o.pca)

plot(o.pca, xlim=c(-2,3), ylim=c(-2,4))

You got a response yesterday telling you that xlim and ylim are not passed to
the plot call from plot.

You can see this yourself by examining the code:

labdsv::plot.pca
function (x, ax = 1, ay = 2, col = 1, title = "", pch = 1, ...) 
{
    if (class(x) != "pca") 
        stop("You must specify a an object of class pca")
    plot(x$scores[, ax], x$scores[, ay], asp = 1, col = col, 
        xlab = paste("PCA", ax), ylab = paste("PCA", ay),
pch = pch,
        main = title)
    invisible()
}
<environment: namespace:labdsv>
