Error in x[i] : object of type 'closure' is not subsettable #22

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
What steps will reproduce the problem?
I'm not yet sure how to reproduce this a simple, public data set, but the error 
has something to do with cross validation.

What is the expected output? What do you see instead?
Very quickly after starting GBM (before it does any training), I get this error:

Error in x[i] : object of type 'closure' is not subsettable

What version of the product are you using? On what operating system?
GBM 2.1
R 2.15.3

Please provide any additional information below.
I will attack the traceback which includes the gbm() invocation.  

If I hear you accept this bug, I am glad to continue to try to get the error to 
reproduce on your system.

As a workaround, is an old version of GBM available?  GBM 1.6 and GBM 2.0-8 
seemed OK, but the recent CRAN update is causing me problems.

Sorry, I forgot to mention this is 64-bit R for Windows 7.

Also, I meant is there a Windows binary package of an old GBM available?

I am able to reproduce the error by loading the packages gbm and doSNOW.  This 
causes object masking, so I think the solution is to make an explicit reference 
to parLapply like parallel::parLapply().  Attached is the code and a log.

Thanks for this. I'll take a look and presumably add parallel::parLapply as you 
suggest.

Old CRAN releases of gbm should be in the CRAN archive:
http://cran.r-project.org/src/contrib/Archive/gbm/

There are still some old non-CRAN releases available from the downloads page of 
this site.

Please see new version of gbm linked from project home page. Let me know if you 
have any further problems.
