You have to define a vector as the same length of your samples, and use as.factor() to convert it to a factor set that you can use with linear models and/or statistical models.

R
To: morphmet@morphometrics.org
Dear all,
I´m trying to read and analyze my landmark data with R. I have upload a tps file from tpsdig2, with 26 landmarks/specimen; ID and scale factor and preformed a procrustes superimposition.
My problem is in analysing groups in subsequent analysis, since group information is included within the ID for each specimen. How do I tell R which specimen belongs to each group? Should I be using other types of dataset? I´m fairly new at R and any help would be most appreciated.
Thank you in advance.
Best,
Raquel Mendes
