Installing R devtools package on WSL - r

Question

The problem:
I'm trying to install the devtools package for R. I'm using Ubuntu 18.04 LTS on WSL, the Windows Subsystem for Linux.
I'm able to install some packages just fine with a simple call to install.packages() from within R on WSL. However, other packages seem to give me trouble.
None of the following methods I've tried seem to work:
* I've tried installing the package with install.packages().
* I've tried installing from source into /usr/local/lib/R/site-library.
* I've tried installing from source into a personal library.
Error message:
I was recieving an error message like that discussed here, but I was unable to fix the problem by editing unpackPkgZip because it didn't exist.
The Question:
How can I install devtools on WSL?

Answer 1

Solution:
I was able to fix the problem by starting over. I uninstalled Ubuntu and then reinstalled it. With a fresh install of Ubuntu 18.04 I followed these instructions. There are other online tutorials which probably work just fine, but I followed this one. You can ignore the bit about installing an rstudio server and the fsl package if you wish.
# Install R on WSL
sudo apt-get update -qq -y
sudo apt-get install -y wget git
OS_DISTRIBUTION=$(lsb_release -cs)
wget -O- http://neuro.debian.net/lists/${OS_DISTRIBUTION}.us-nh.full | sudo tee /etc/apt/sources.list.d/neurodebian.sources.list
sudo apt-key adv --recv-keys --keyserver hkp://pool.sks-keyservers.net:80 0xA5D32F012649A5A9
sudo apt-get update
sudo apt-get install libopenblas-base r-base
sudo apt-get update -qq -y
sudo apt-get install -y libgit2-dev
sudo apt-get install -y libcurl4-openssl-dev libssl-dev
sudo apt-get install -y zlib1g-dev libssh2-1-dev libpq-dev libxml2-dev
#sudo apt-get install -y libhdf5 # This didn't work.
Now try installing devtools in R.
# Install devtools
install.packages("devtools", repos = "https://cran.rstudio.com/")
Permission error:
If you encounter a permission error like the following...
Warning in install.packages("edgeR") :'lib = "/usr/local/lib/R/site-library"' is not writable Would you like to use a personal library instead? (y/n)
...you need to provide the user with write access to the directory where R packages are installed (see here). Try changing the group ownership of this directory:
# Who has ownership of /usr/local/lib/R/site-library/?
ls -l /usr/local/lib/R/
# drwxrwsr-x 1 root staff 512 Jul 18 21:38 site-library
# Change ownership.
sudo chgrp twesleyb /usr/local/lib/R/site-library/
ls -l /usr/local/lib/R/
#drwxrwxr-x 1 root twesleyb 512 Jul 18 21:38 site-library
# In this case I have write access, but in case you need to add it, try:
# $ sudo chmod g+w /usr/local/lib/R/site-library
You should now be able to install.packages("package").
I'm a linux novice, but I think this is an okay thing to do.
Update:
You can also try following duckmayr's instructions.
