Apologies, unserialize takes a connection, not a file, so you would need
something like:
# linux (not run)
f <- file("rawData.rds", open="r")
rawData <- unserialize(f)
close(f)
The help file states that readRDS will read a file created by serialize
(saveRDS is a wrapper for serialize).
It appears that the problem was "byte-shuffling at both ends when
transferring data from one little-endian machine to another" and was
worked around by using xdr = FALSE. So, this wouldn't necessarily work
when transferring between big-endian and little-endian machines.

Many thanks to Berwin, Eric, Robert, and Jan for their input.
I had hoped it was as simple as because I typed
saveRDS("rawData", file = "rawData.rds") on the Windows side.
but that wasn't the case.
Robert Burbridge suggested:
windows (not run)
f <- file("rawData.rds", open="w")
serialize(rawData, f, xdr = FALSE)
close(f)
# linux
rawData <- unserialize(file = "rawData.rds")
That didn't work:
Error in unserialize(file = "rawData.rds") :
unused argument (file = "rawData.rds")
(the argument isn't 'file')
Nor did
rawData <- unserialize("rawData.rds")
Error in unserialize("rawData.rds") :
character vectors are no longer accepted by unserialize()
However
readRDS(file = "rawData.rds") did!
So what I needed was serialize but not unserialize.
I still don't know Why, but I know How.
