ggplot2 fails to load

Question

ggplot fails to load. I uninstalled ggplot2 and reinstalled. Then uninstalled ggplot2 again, uninstalled R 3.2.2, reinstalled R 3.2.2, reinstalled ggplot2. Same errors. scales.rdb corrupted, internal error -3.

This is the first time I attempted to use ggplot2 with Windows 10 OS. Error message + sessionInfo below. I see that the sessionInfo has R running under Windows 8, but Windows 10 is installed. I don't know if that is meaningful.

Any feedback is appreciated.

I figured it out. the scales.rdb file was corrupted. re-installing scales as install.packages("scales") did not work. install.packages("scales", dependencies = TRUE) did work.

Answer 1

I had a similar issue with my R studio This worked for me--

1. Tools->Check for Package updates-->select all and update
2. Restart R session with .rs.restartR()
3. install ggplot2 again and problem solved!
