R is broken

[chrisroadmap]

The calibration ecosystem relies on the EBM R package which is installed from GitHub (https://github.com/donaldcummins/EBM/tree/v1.1.0).

R package GitHub installability relies on devtools. devtools does not seem to be supported by R>=4.4.0. However, the package Matrix is an indirect dependency of EBM and appears to require R>=4.4.0. This conflict does not on the face of it seem to be resolvable.

Possible solutions:

• keep hacking away
• wait for devtools to support R 4.4
• convince Donald C or some kind soul to re-write the EBM package in python
• carry on using my MacBook for the calibration step (running R 4.1.1 and older versions of dependencies) - hardly reproducible
