md5sum issues
Thank you Jeff for the pointer. If it's not an R issue, I guess it will be difficult to solve... But maybe there is a workaround using R, like using another function or editing the files...? Does anyone have any idea?

Sounds like a newline discrepancy issue. Highly unlikely to be an R issue. On February 2, 2021 8:01:05 AM PST, Ivan Calandra <calandra at rgzm.de> wrote:
Dear useRs, I have some kind of a weird issue with md5sum() and I'm not sure where I should start. I have a repository on GitHub, with a local Git installation and connected with RStudio. I am working on Windows 10 and a colleague of mine works on Linux. We both pull the latest commits of all files, but the checksums are different. Even stranger (to me at least), I get a different checksum from the local file (downloaded through Git via pulling) and the same file that I manually download from GitHub. The checksum of the manual download from GitHub is the same as that of my colleague on Linux. This happens to all text-based files (Rmd, MD, CSV...) but not to non-editable files (PDF, XLSX...). For example (I have shortened the paths):
library(tools) md5sum(file.choose()) # local repo
D:\\...\\SSFAcomparisonPaper\\README.md "e3b08fc2ab8b3c8b57e681f862a77f32"
md5sum(file.choose()) # downloaded from GitHub
C:\\Users\\...\\Downloads\\README.md "05fab51e18b962a9f3266c7b79016ce6"
md5sum(file.choose()) # local repo
D:\\...\\SSFAcomparisonPaper\\...\\SSFA_GuineaPigs_plot.pdf "d9b331642bfd0d192e4eff5808b2a30f"
md5sum(file.choose()) # downloaded from GitHub
C:\\Users\\...\\Downloads\\SSFA_GuineaPigs_plot.pdf "d9b331642bfd0d192e4eff5808b2a30f" I am not sure whether it is an issue with the algorithm of md5sum(), whether it's a R/RStudio/Git/GitHub/Windows issue, so I would be grateful if you could help me sorting it out. Thank you in advance, Ivan
