I'm trying to install papaja package on my windows machine. But I'm getting the following error message

Installing 3 packages: bookdown, rmdfiltr, zip
Installing packages into ‘C:/Users/cophuser/Documents/R/win-library/3.6’
(as ‘lib’ is unspecified)
Error: Failed to install 'papaja' from GitHub:
  (converted from warning) unable to access index for repository http://www.stats.ox.ac.uk/pub/RWin/bin/windows/contrib/3.6:
  cannot open URL 'http://www.stats.ox.ac.uk/pub/RWin/bin/windows/contrib/3.6/PACKAGES'

I used this command to install papaja 

# Install devtools package if necessary
if(!"devtools" %in% rownames(installed.packages())) install.packages("devtools")

# Install the stable development verions from GitHub
devtools::install_github("crsh/papaja")

# Install the latest development snapshot from GitHub
devtools::install_github("crsh/papaja@devel")

Please let know what should I do if you know how to solve this issue

I had the same problem, and I solved it by updating my Rtools to v.4.

Check here: https://cran.r-project.org/bin/windows/Rtools/
