Hi all. I have shiny server installed and working on a virtual machine. In my global.R file, I want to load an RDS file. In the log, the error I get is 'unknown input format.' I next decided to change the .rds file into an RData file. I am getting the error:

"Warning: file 'file.RData' has magic number 'versi'
  Use of save versions prior to 2 is deprecated
Error in load("file.RData") :
  bad restore file magic number (file may be corrupted) -- no data loaded"

I saved the .RData file on R version 4.0.0 and am using R version 3.6.3 on my virtual machine. Is there a way to fix this? Also is there a better way to store a large file (> 1GB) and load it into my shiny app? Any insight is appreciated. Thanks.
