fairness package install not working with R version 3.6.3

[mjorgen1]

I'm new to R and want to try out the fairness package with some data. I ran the below command and received that long stream of output. After reading through the output, I tried installing the two packages it recommended I download 'libxml2-dev' and 'libcurl4-openssl-dev' but those are not available for my version of R. I'm on an Ubuntu 20.04 machine using R 3.6.3. Is there some incompatibility with R 3.6.3 and the fairness package and its dependencies? Please let me know, thanks!

Hi @mjorgen1, thank you for reporting this.

I have tried installing the package with R 3.6.3 on Windows / Mac OS and did not run into this issue, so it appears to be linked to Ubuntu and the way some of the dependencies are compiled for this OS. I will try looking into this as soon as possible. Kindly let me know is you find a solution in the meantime.

Best wishes
Nikita
