R help - Jan 2018 - Newbie wants to compare 2 huge RDSs row by row.

Each RDS is 40 MBs. What's a slick code to compare them row by row, IDing
row numbers with mismatches?

Thanks in advance.

Hi Marsh,
An RDS is not a data structure such as a data.frame. It can be anything.
For example if I want to save my objects a, b, c I could
do:
> saveRDS( list(a,b,c,), file="tmp.RDS")
Then read them back later with
> myList <- readRDS( "tmp.RDS" )
Do you have additional information about your "RDSs" ?

Also, it will be easier to provide helpful information if you'd describe
what in your data you want to compare and what you hope to get out of the
comparison.

Best wishes,
