I need to run SEM (with PLS) analysis, and was provided script that is used the plspm package. I tried to install but it says it's no longer available for current R update.
Warning in install.packages :
package ‘plspm’ is not available (for R version 4.0.2)
Also on further investigation it's no longer stored on cran.
https://cran.r-project.org/web/packages/plspm/index.html
Package ‘plspm’ was removed from the CRAN repository.
Formerly available versions can be obtained from the archive.
Archived on 2020-05-14 as long orphaned and those depending on it have been given notice.
Should I install an older version of R to run this package?, and download plspm independently (outside cran)? If plspm out of date is there a problem with using this package? Is there a better package to run SEM with PLS?
