Dear colleagues,
I a m a beginner with R and I would like to add labels (i.e. the variable names) on a pca loading plot to determine the most relevant variables. Could you please tell me the way to do this kind of stuff.
    The command I use to draw the pca loading plot is the following :
    Plot(molprop.pc$loading[,1] ~ molprop.pc$loading[,2])
    Thanks for your help
    Fred Ooms
