[R] saveRDS() and readRDS() Why?

[Patrick Connolly]

>From a Windows R session, I do
 
> object.size(rawData)
31736 bytes  # from scraping a non-reproducible web address.
> saveRDS(rawData, file = "rawData.rds")

Then copy to a Linux session

> rawData <- readRDS(file = "rawData.rds")
> rawData
[1] "rawData"
> object.size(rawData)
112 bytes
> rawData
[1] "rawData" # only the name and something to make up 112 bytes
> 

Have I misunderstood the syntax?

It's an old version on Windows.  I haven't used Windows R since then.

minor          2.4                                        
year           2016                                       
month          03                                         
day            16                                         


I've tried R-3.5.0 and R-3.5.1 Linux versions.

In case it's material ... 

I couldn't get the scraping to work on either of the R installations
but Windows users told me it worked for them.  So I thought I'd get
the R object and use it.  I could understand accessing the web address
could have different permissions for different OSes, but should that
affect the R objects?

TIA
