Installation meta-information error

[thoughtcaster]

When I try to install the fingraph package using devtools::install_github("convexfi/fingraph") in RStudio, I get the following output:

Using GitHub PAT from the git credential store.

See section 'The DESCRIPTION file' in the 'Writing R Extensions'
manual.
Error: Failed to install 'fingraph' from GitHub:
! System command 'Rcmd.exe' failed

Argument 3 is the email address according to Google. I checked the file and it is there but it is passed using a keyword argument. Perhaps this is the problem. For reference I am running R 4.5 with the latest version of RTools.

Also, this package has been archived on CRANN because it depends on spectralGraphTopology which has also been archived on CRANN, so perhaps this should be addressed so that I and others could install this package the normal way. I am enjoying the book so far and would like to try out applying the algorithms to real data.

First, you need to check to have Rtools installed.
(See: https://cran.r-project.org/bin/windows/Rtools/)

Then, download the archived package file in .tar.gz format from CRAN:
https://cran.r-project.org/src/contrib/Archive/fingraph/

Next, navigate to the directory where you downloaded the package file and run the following command in R
install.packages(package_file_name, repos = NULL, type="source")

where package_file_name is something like "fingraph_0.1.0.tar.gz"
