R help - Jan 2005 - printing PCA scores

Hey folks,

I have an environmental dataset on which I conducted a PCA (prcomp) and I
need the scores of this PCA for each site (=each row) to conduct further
analyses.

Can you please help me with that?

Thanks a lot

Did you try help(prcomp) ?

It says that prcomp (may) return an item called 'x':

x: if 'retx' is true the value of the rotated data (the centred
          (and scaled if requested) data multiplied by the 'rotation'
          matrix) is returned.

[non-matching parentheses in the original help file]

So this is what you asked for.

cheers, jari oksanen
