Subject: PCA in R vs RWA in
tpsRelW
To: "[email protected]"
<[email protected]>
Hi everyone!
I'm working on a project in which I use sliding semilandmarks. I've run the
dataset through the tpsRelW software and through R using the geomorph package,
but I get different results using each. I've fixed the slider file to allow for
sliding semilandmarks
in geomorph. My understanding is the RWA is equivalent to PCA, so would there
be a difference in a PC1vPC2 versus a RW1vRw2 plot?
Thanks for the help!
