I am trying to install an old version of smacof ( smacof_1.2-3.tar.gz )but I get the following message:
install.packages("D:/username/Statistics/Mutlivariate analysis/MDS/smacof_1.2-3.tar.gz", repos = NULL, type = "source")
ERROR: dependencies 'rgl', 'scatterplot3d' are not available for package 'smacof'
** removing 'D:/username/Smargorp/R/R-4.0.3/library/smacof'*
Warning in install.packages :
- installation of package ‘D:/username/Statistics/Mutlivariate analysis/MDS/smacof_1.2-3.tar.gz’ had non-zero exit status*

What could be the problem?
