r

I noticed something in R , say pc is the result of applying PCA to a data matrix and pc$x is my sample principal component matrix .

when try plot(pc$x) , it will only plot the first principal component (pc1) against the second (pc2) , but I actually have more than 2 principal components. how do I show all of them ?
