You can't. Use R on your computer instead.

Hi Frank,

You could upload your R source file to a public URL, for example to
github and read via RCurl,
as source do not support https as far as I know. Here is a working example.

library('RCurl')
tmatrix <- getURL("https://raw.githubusercontent.com/msuzen/isingLenzMC/master/R/isingUtils.R")
eval(parse(text=tmatrix))

Not that you need to use raw URL for github file.

Best,
-m

well... but your knowledge is severely (:-) outdated.
Why did you not try first?

source("https://raw.githubusercontent.com/msuzen/isingLenzMC/master/R/isingUtils.R")

works for me even in R 3.3.0 which is really outdated itself!

Re: run r script in r-fiddle

Suzen, Mehmet
We were talking about r-fiddle. It gives error there [*], that's why I
suggested using RCurl.

> source("https://raw.githubusercontent.com/msuzen/isingLenzMC/master/R/isingUtils.R")
...
unsupported URL scheme
Error : cannot open the connection

 Note that, looks like r-fiddle runs R 3.1.2.

and later you note that it seems to run R-3.1.2 --- which is
ridiculously outdated.

I think R-help should not be (mis)used at all to talk about
R-Fiddle, then.
Notably as I think it's been provided by a company that no
longer exists under that name, and even if that'd be wrong,  R-Fiddle
does not seem free software (apart from the R parts, I hope !).

If another asked about his/her problems using R 3.1.2, I think
we would all tell him to go away and install a current version
of R, and not waste any more bandwidth and R-help readers' time,
wouldn't we ?

For the record, r-fiddle is maintained by datacamp:

Try that source statement here -- it is running R 3.4.1:

Re: run r script in r-fiddle

In reply to this post by Suzen, Mehmet
Dear List,

According to datacamp support team, r-fiddle.org is not supported. We
asked them to put it down as Professor Maechler suggested it is
a waste of time for the R-help to respond to questions on something
not maintained and severely outdated. If you would like to use
R from your browser, you can embed the following into a web page:

<script src="https://cdn.datacamp.com/datacamp-light-latest.min.js"></script>
<div data-datacamp-exercise data-lang="r"></div>

Currently, it supports R 3.4.0. See the code base, which is open
source, here https://github.com/datacamp/datacamp-light

Hope it helps.

Best,
Mehmet

Yes, it does!
Thank you very much, Mehmet, for reaching out to get these
clarifications and reporting back here.

I'm glad to be notified that datacamp seems to adhere to an open source
philosophy also in the tools they write: For datacamp-light they
_do_ adhere (*) to the much more strict
GNU Public Licence (GPL) Free Software standard which emphasizes not
only the free availability of source code, but also other
freedoms, e.g., to *modify* and re-distribute under the GPL, see
https://en.wikipedia.org/wiki/GPL for much more.

An open Github repos alone is _no_ guarantee for that, and
unfortunately I think there's much software there where authors
don't care (or don't want) to use a "truly" free software
licence such as
(*) https://github.com/datacamp/datacamp-light/blob/master/LICENSE.md

Best,
Martin Maechler
