[R] Error installing ggplot2 package

[Marc Schwartz]

Hi,

If I am reading the messages below correctly, it would seem that Amelia did install ggplot2.

However, what is not clear is the source and version of the ggplot2 package that she installed.

The message would suggest that she installed a version of ggplot2 that was built for R-devel, which is to be R version 3.5.0 and thus, is not compatible with the current release/patch versions of R.

Also, according to the NEWS file for R-devel:

  http://stat.ethz.ch/R-manual/R-devel/doc/html/NEWS.html

specifically right at the top:

"• The default version for save(), saveRDS(), serialize() and similar has been changed to 3. Objects saved with version 3 are not readable by earlier versions of R.

This includes saved workspaces."


That might also explain the readRDS(pfile) related error message.

If Amelia downloaded the *wrong* (e.g. R-devel) Windows binary version of ggplot2 from CRAN (currently ggplot2_2.2.1.zip) with the intent to install it locally, for example, rather than just using:

 install.packages("ggplot2")

as Bert notes below, that might explain the errors.

Amelia, can you provide more details?

Regards,

Marc Schwartz
