IPO error message for UseMethod("sendData")

[leichtle]

Dear developers team, Running the IPO scripts ('optimize XcmsSet()') I run into the error:

Fehler in UseMethod("sendData") : nicht anwendbare Methode für 'sendData' auf Objekt der Klasse "c('forknode', 'SOCK0node')" angewendet (in German, meaning "Error in UseMethod("sendData") : not applicable method for 'sendData' on an object of class "c('forknode', 'SOCK0node')"").

Description:

• System: R 3.2.4 on Debian 8.4, all packages actualized.
• Packages load properly.
• A new DoE is started when the function 'optimize XcmsSet()' is called.
• Package 'snow' is attached.
• A snow cluster is started with [nSlaves] local sockets.
• Image 'rsm_1.jpg' is drawn.
• A new DoE is started automatedly with a different parametrization.
• After the expected runtime, the run stops with the above-mentioned error message.

Suspicion: IPO calls 'parallel', and after the execution of the DoE code, 'snow' is attached. I suppose, 'snow' should be detached before a new DoE run starts. A similar issue has been described for package {secr}. Any help would be greatly appreciated! Best regards, Alex

Ok, IPO is now on version 1.7.5 and your issue should be fixed. Can you confirm that?
