Hi all!

I'm working with geomorph to perform a GPA including landmarks and surface semilandmarks in 3D. Unfortunately, some of the specimens include a few coordinate values of -999.xxx, which are interpreted by the gpagen function as missing values:

if (length(grep("-999", A)) != 0) {
        stop("Data matrix contains missing values. Estimate these first(see 'estimate.missing').")
    }

does anyone have an idea on how to circumvent this?

thanks!

Leandro
