I think you're right. The warning says the `actuar` package (for example) is unavailable. Looking at the CRAN page (https://cran.r-project.org/package=actuar), it needs R 4.1.0 or newer. Not sure if ChainLadder will work with an older version - you could try this: https://stackoverflow.com/questions/17082341/installing-older-version-of-r-package to install the packages mentioned in the warning (actuar, pbkrtest and RcppEigen), then retry your install – Hobo Mar 01 '23 at 22:19
Or, you could just update R. – Phil Mar 01 '23 at 22:42

Look up date of your R version and then use that to pick contemporaneous package versions from the archive. (Or update R, since yours is a couple of years out of date.) – IRTFM Mar 01 '23 at 23:20
