plot.pca.loadings

Plot Residue Loadings along PC1 to PC3

Plot residue loadings along PC1 to PC3 from a given xyz C-alpha matrix of loadings.

## S3 method for class 'pca.loadings'
plot(x, resnums = seq(1, (length(x[, 1])/3), 25), ...)

`x`	the results of principal component analysis obtained from `pca.xyz`, or just the loadings returned from `pca.xyz`.
`resnums`	a numeric vector of residue numbers.
`...`	extra plotting arguments.

Called for its effect.
