Description Usage Arguments Examples

A tool used to plot the cross product of the normalized data and the eigenvectors, it relies only on the standard library ploting function

1	plotPCs(pcs, pos, data, cats, lab = c("xlabel", "ylable", "Title"))

`pcs`	the eiginvectors
`pos`	a list indicating which two dimensions should be ploted
`data`	the normalized data
`cats`	the catagories, used to label the plot
`lab`	the labeling information

heightFile<-"~/Dropbox/UTX-Alex/jan/combined_heights.bed"
catFile<-"~/Dropbox/UTX-Alex/jan/catagories"
cats<-as.character(unlist(read.table(catFile)))
score<-loadHeightFile(heightFile)$data
normData_eigen<-pca(score)
plotPCs(normData_eigen[[2]],c(1,3),normData_eigen[[1]],cats)
