Perhaps you got bitten by Dolphin's non-modal dialogs, as described in
https://userbase.kde.org/Dolphin/File_Management:
Non Modal Dialogs
When Moving, Copying or Deleting files/directories the dialog disappears
even when the operation has not yet completed. A progress bar then appears
in the
This is getting more strange.
I normally copy from the shared folder to the appropriate directory
using Dolphin, the KDE file manager. If instead I use the standard bash
cp command, no corruption happens -- at least with the limited testing I
have done. There also seems to be no problem
It seems like copying the files corrupted them. How did you copy them (with
R
or cp or copy or ftp, etc.)? I don't see how this has anything to do with
R.

The solution was very simple. Don't use the same name for the rds
file as used for the R object, viz a vie:
saveRDS(x, file = "x.rds")
and
x <- readRDS(file = "x.rds")
will not work; however
saveRDS(x, file = "y.rds")
and
x <- readRDS(file = "y.rds")
will work.
An undocumented feature?

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).

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")
Patrick,
I cannot reproduce this behaviour. I'm using:
Windows 8.1; R 3.5.1; RStudio 1.1.463
running in a VirtualBox on Ubuntu 18.04 with R 3.4.4; RStudio 1.1.456
The file size of rawData.rds is always 88 bytes in my example and od
gives the same results on Windows and Linux.
I am using a
Are you sure you didn't do saveRDS("rawData", file = "rawData.rds")
instead of saveRDS(rawData, file = "rawData.rds") ? This would explain
the result you have under linux.
In principle saveRDS and readRDS can be used to copy objects between
R-sessions without loosing information.
What
If the file sizes are the same, then presumably both contain the binary data.
From the serialize function help:
"As almost all systems in current use are little-endian, xdr = FALSE can be used to
avoid byte-shuffling at both ends when transferring data from one little-endian machine
to
Your understanding is correct. It works fine for me.

They're both about 3kb.

Hi Patrick,
From the help: "save writes a single line header (typically "RDXs\n")
before the serialization of a single object".
If the file sizes are the same (see Eric's message), then the problem
may be due to different line terminators. Try serialize and unserialize
for low-level control
What do you see at the OS level?
i.e. on windows
DIR rawData.rds
on linux
ls -l rawData.rds
compare the file sizes on both.
