Mauro, plus others, As a follow up, we are also working on a new function in geomorph to allow users to modify transformation (deformation) grids. Much like the R par function, this function will allow users to vary the colors, width, and style of grid lines and link links, the density of grid points, and the color and size of landmarks. This function will be available in the near future.

The problem is that I was calling by mistake a routine from Ian Dryden's shapes package (procGPA) to generate the Procrustes-aligned coordinates, instead of the gpagen routine. Fixed this and now everything works fine. I take this opportunity to ask another question, this time relating to the plots generated by geomorph. Is there a way to customize them, including for example axis labels in the PCA plots? In fact, the "Quick Guide" shows these plots with labels, but I could not figure out how to include them in my plots. Calling the R par function (as one should have done when using the usual "plot" command) did not work. Again, thanks for your help.

If you have your data as a 2D matrix, you simply use arrayspecs to make it a 3D array.

First one concerns Principal Components Analysis, using the plotTangentSpace routine. It requires a 3D matrix as argument, however my data (on fishes) are 2D and I could not figure out how to convert my data to the required format; the explanation of the arrayspecs routine in the "Quick Guide to Geomorph" was not clear for me (and it lacks a workin exemple). My data are read from a NTSYSpc file containing 2D coordinates for 10 landmarks for a number of fish specimens, using the readland.nts routine. I have been able to perform a PCA on these data using the shapepca routine in Ian Dryden's shapes R package, but would like to perfom the entire analysis using geomorph.
