Instead of using the function "installed.packages()", use the function "install.packages()" for installing any package in R. For example, instead of writing "installed.packages("ggplot2")", write "install.packages("ggplot2")".

To avoid any issue with package installation in the future kindly do the following -

1) Install the latest version of "Rtools" from here - https://cran.r-project.org/bin/windows/Rtools/

2) Also, install "devtools" package by executing the following command - install.packages("devtools")

I tried a different CRAN mirror for my installation. Look at this solution > Problems with installing and loading ggplot2 in the RStudio Community and explained in a case study by a UK techwriter https://cheapessaywriter.co.uk/ online help.
