I am trying to install psych package in R 3.6.2 but after installing the same my library function is giving below error for psych:
So i tried installing "mnormt" package which i am not able to install and getting below error:
Any help would be appreciated :)
Try to add the tag version to install command, for example:
devtools::install_github('cran/mnormt@R-3.0.3')
Check what version you need and replace the tag after the '@'.
Also. try restarting R if possible.
If you still get erros,try
Install an older version of the package, one compatible with the version of R I am running.
R version is 3.6.3 was released on feb 2020. Try upgrading your R to version 4.x which is latest.
I go to the mnormt
page and click on "old sources" https://cran.r-project.org/src/contrib/Archive/mnormt/
I see that version 2.0.0 is the most recent release which is prior to my version of R
Following these pages: "Installing older versions of packages" https://support.rstudio.com/hc/en-us/articles/219949047-Installing-older-versions-of-packages I copy the relevant url into this code and run it in R
packageurl <- "https://cran.r-project.org/src/contrib/Archive/mnormt/mnormt_2.0.0.tar.gz"
install.packages(packageurl, repos=NULL, type="source")
