r - Error while running Azure Machine Learning web service but the experiment works fine -

i have created azure ml experiment r script module works fine while run experiment when publish web service throws error http 500 ( believe error causing in r script module because other modules running fine in web service can't debug problem

http status code: 500, timestamp: fri, 08 may 2015 04:23:14 gmt

also there limitation in r e.g. function wont work in web service

i found problem. facing error because r module in azure ml was taking variable other data type , not producing outputs results checking through loop why getting error.
