Great job Vincent !
It will be great when it will work on OS X ;)
There is some problems on Mac OS X: - when I try to load in a fresh Pharo 5.0 image, I got a DNU on: RObjectArray class>>initElementType: I was able to load the package after a while by loading directly the package with the Monticello Browser
Strange, I deleted these methods... Please ensure you are using a Pharo 6.0 image (it should work under Pharo 5.0 too) and that version 14 of ConfigurationOfRProjectConnector and version 71 of the RConnector packages are loaded.
- Apparently there is still some methods using NB like: RSession class>>checkSession or RSession class>>initEmbeddedR:
Should not, it is modified ...
I try to move the R dll close to my Pharo VM and also inside the Plugins directory but without success ...
It should be at the same location that libcairo.2.dylib
Is there a way to say where are the R dll instead of copying them ?
Are you using the system to do the library path resolution? Or finding the library file in Pharo and then passing an absolute path to FFI? cheers -ben
Didn't think so .. Maybe the VM developers knows ?
Thanks!
Vincent
Thank you.

Hello everyone,
I am glad to announce the release of version 2.1 of the RProjectConnector.
The binding between Pharo and R (https://www.r-project.org/) is now translated to UFFI and so to Pharo 6.0.
You can call directly your R methods from Pharo. For example, with the famous iris clustering example:
iris := 'eval' asREval: {RObject findVar: 'iris'}.
'plot'
asREval:
{(iris at: 'Petal.Length').
(iris at: 'Petal.Width').
(#pch -> 21).
(#xlab -> 'length').
(#ylab -> 'Width').
(#bg ->((iris at: 'Species') collect: [ :value | {'red'. 'green3'. 'blue'} at: value ])).
(#main -> 'Edgar Anderson''s Iris Data')}.
iris inspect.
To use it, you should install R and copy the R libraries near the Pharo VM (see the documentation on SmalltalkHub (http://smalltalkhub.com/#!/~VincentBlondeau/RProjectConnector) for how to proceed).
Donât forget to relaunch Pharo after the installation to be able to use the connector.
Only basic features are implemented yet, but you can participate to its extension!
Cheers,
Vincent Blondeau
