To cite package 'geomorph' in a publication use the first two references. If analyses with RRPP were used, cite the subsequent three references:

Baken E, Collyer M, Kaliontzopoulou A, Adams D (2021). “geomorph v4.0 and gmShiny: enhanced analytics and a new graphical interface for a comprehensive morphometric experience.”

Adams D, Collyer M, Kaliontzopoulou A, Baken E (2022). “Geomorph: Software for geometric morphometric analyses. R package version 4.0.4.” https://cran.r-project.org/package=geomorph.

Collyer ML, Adams DC (2021). “RRPP: Linear Model Evaluation with Randomized Residuals in a Permutation Procedure, R package version 1.1.2.” https://cran.r-project.org/package=RRPP.

Collyer ML, Adams DC (2018). “RRPP: An R package for fitting linear models to high‚Äźdimensional data using residual randomization. .”

As geomorph is evolving quickly, you may want to cite also its version number (found with 'library(help = geomorph)'). Additionally, the RRPP package should also be cited for any analyses using RRPP. (See 'library(help = RRPP)' or 'citation('RRPP')'.)
