Steps to Update Matrix Package and Install Required Packages:

The installation of required packages is failing due to an outdated version of the Matrix package. The current version is 1.4-1, but the installation requires version 1.6.0 or later.

Resolution:

Follow the steps below to update the Matrix package to the required version and reinstall the necessary packages.

Step-by-Step Guide:

1. Update the Matrix Package:

To update the Matrix package to version 1.6-0, use the following command to install the package from source:

install.packages("https://cran.r-project.org/src/contrib/Archive/Matrix/Matrix_1.6-0.tar.gz", repos = NULL, type = "source")

2. Load the Matrix Package:

After installation, load the Matrix package into your R environment by running:

library(Matrix)

3. Check the Installed Version of Matrix:

Verify that the Matrix package is updated to version 1.6-0 by checking its version:

packageVersion("Matrix")

4. Install Additional Required Packages:

Next, install the required packages quantreg, car, and nmFun:

install.packages("quantreg")
install.packages("car")
install.packages("nmFun")

5. Verify Installation of nmFun:

Check if the nmFun package has been successfully installed by running the following command:

"nmFun" %in% installed.packages()

If the package is installed, the following command will display its version:

if ("nmFun" %in% installed.packages()) {
  packageVersion("nmFun")
} else {
  cat("nmFun is not installed.")
}
