So - it seems that there was some network glitch when I was upgrading to Sage-9.6 and R packages didn't get installed without breaking the build. I couldn't see the actual problem, but each installation command was taking about 3 seconds, while usually it is longer and different for different packages. I've rebuilt the containers and now ggplot2 is working as expected: https://sagecell.sagemath.org/?z=eJw1jt0KwjAMhe8F3yH0qsUoa2W78l0kuqwW2nXUguzt7Y_e5IR8Jznx7pEo7dLazcds1PFAluF2hqc0I8J1QBinMrW8zpw6EIE8CwSx8L9rWmwfdvaVu01PZVnrUowZCgv7TJkqq3pZEgWWJQ37bey7Nav9IrsfgfjdbD-uTmA5hvsW3Zql-gLEODmZ&lang=r&interacts=eJyLjgUAARUAuQ==
If somebody has some tips on how to detect in `r.eval("install.package(...)")` that the package was not actually installed well, feel free to share ;-) -- You received this message because you are subscribed to the Google Groups "sage-cell" group.
