I won't get back to my office, and the hard drive where the files are
stored, for about a week. I'll send something along then.
Thanks, Emma.

Hi David,
Not sure what the file actually looks like since you’ve not included a sample
here. However I suggest taking a look at the readland functions in geomorph R
package to see how we tackle the different types. If you want, send it through
to us and we can take a look. If there’s a lot of
Hi everyone,
I've collected 3D landmarks on a series of cranial surface models in Avizo.
Avizo's landmark editor outputs .landmarkAscii files, which I would like to
read into R. The way I've done the reading has the following very
unexpected effect: *sometimes, *it* writes *additional data to my

Dear Brenna,
It appears the problem is that you are attempting to use prcomp on your
points(p) x dimensions(k) x n Procrustes coordinates without converting these
data into a n x pk matrix, required by prcomp. Unfortunately, prcomp will use
the first p x k part of the array of coordinates, res
Hello,
I am trying to perform a PCA on a basic set of 30 configurations, 3
specimens each with 10 configurations of landmarks. I was wondering why I
am getting different PCA results between plotTangentSpace() and prcomp().
When I perform plotTangentSpace(), it gives me a comprehensive list of 3
Hi,
This subject pops up every few months on Morphmet. The general consensus is
that either Creaform or structured light scanners like Artec or LMI have
made are generally very satisfactory solutions. People like Breuckmann are
an order of magnitude more expensive but also very good.
You'll want to
Dear Emma and Andrea,
Thanks for the rescue. I'll give this a try. I don't really know much about
code so some of the syntax is confusing to me, but this looks to be an
explanation I can follow after a few tries. Thank you so much.
Best,
Ari

Hi Miguel,
I've been using a Creaform GoSCAN50, and am very happy with it (I scan ceramics
though; not hominins). There are two of these scanners (GoSCAN20 and GoSCAN50 -

Dear Ari,
geomorph uses the following code to write an .nts from the digtizing
functions. It's an .nts file for single specimens

# A is an nx2 or nx3 matrix of the output coordinates. To be used

Hi all,
I'm hoping this will be a quick and easy question. I've even done it before
and then forgotten how.
I need to create quite a few .nts files. The easiest way to do this I think
is in R. I read in my .dta file, got my landmarks all switched the way I
want them but now for each of my element
