I recently updated my R to 3.5.0, along with all the packages I use. I had several .rda files I was working with in a project that were saved before 3.5.0 that I load into the session. These files are working as intended
But for data.frame/tibble files I've saved since 3.5.0, after using load("<file.rda>") my R Studio throws the error.
- Error in class(obj) <- "rs.scalar"
After throwing that error, every command returns that error until 3 or 4 commands have been issued, and then R session crashes.
I've noticed the same behavior doesn't occur with vectors or matrices, so I would guess it's some change in the implementation of how the 'save' function handles data.frames for 3.5.0. I'm not sure how to include a 'reproducible' example of this, but essentially is looks like this
library(tidyverse) #>library(...) load("oldfile.rda") #> Run any code I want load("newfile.rda") #>Everything returns ' Error in class(obj) <- "rs.scalar" '
SessionInfo detailed below as well. AVRC packages are packages I wrote and maintain for my work. I've rebuilt them all under 3.5.0, so I don't believe that's part of the issue.
This is my first time asking a question here, so I wasn't sure if this fits better in the R Studio IDE or General section. Please let me know if there's anything I forgot, or something else that could be helpful to find a solution. Thank you
