Dear Morphometricians,
I am attempting to upload 2D landmark and semi-landmark data into R (geomorph
package), and I was wondering if anyone could give me advice. In past analyses,
I have uploaded both a landmark tps file, which contains all of the landmark
and semi-landmark data combined (measured using tpsDig2), along with a sliders
csv file (made using tpsUtil), which indicates which points should be treated
as semi-landmarks. I am hoping to start using the "draw background curves"
(yellow pencil) tool in tpsDig2, which puts the curve information directly into
the landmark tps file. Does anyone know whether or not I need to indicate
within R that these curves exist? And if so, how?
I've tried using the following functon:
> slide <- as.matrix(read.tps("semilandmarks.tps"))
but when I try to use the gpagen function:
> procrustes <- gpagen(landmarks, curves=slide, PrinAxes = FALSE)
the program crashes.
Thank you in advance for any help you can provide.
Best,
Miranda Karban
