nFactors-Installation package error message in R

[panosemmanouilidis]

Hi all,
I try to run nFactors function in RStudio.However when I run library(nFactors) it appears
the following error message:
Loading required package: lattice**
Error: package or namespace load failed for ‘nFactors’ in loadNamespace(j <- i[[1L]], c(lib.loc, .libPaths()), versionCheck = vI[[j]]):**
there is no package called ‘mnormt’**
Any idea how can I resolve this issue?
Many thanks in advance
Panos

@panosemmanouilidis

there is no package called ‘mnormt’**

Install the missing dependency

install.packages("mnormt")

[panosemmanouilidis]

There is no mnormt package! This is indicated in the last line and I checked it by myself.
Thanks

I don't understand what you mean. What have you checked by yourself?

mnormt is an R package available at CRAN and it's a dependency for nFactors so you need to install it using the command I gave you in my previous post. Do you get any error message installing it?

[panosemmanouilidis]

Actually It says that mnormt is not available for R3.6.3. version so i have no clue what i will do.I tried to use pkgbuild but unsuccessfully

It says here https://cran.r-project.org/web/packages/mnormt/index.html that the package requires R 4.0 or higher. So to install, you should upgrade from 3.6.3 to 4.0.2 (the most recent version).
