options('redis:num'=TRUE) has to be used

[andreyto]

Otherwise, running example foreach loop returns an error:

> foreach(j=1:10,.combine=sum,.multicombine=TRUE) %dopar%
+     4*sum((runif(1000000)^2 + runif(1000000)^2)<1)/10000000
Error in sprintf("%s:%.0f.env", queue, ID) : 
  invalid format '%.0f'; use format %s for character objects

The error is generated inside redisWorker() function.
Maybe the documentation can be updated to require options() call?

I see that this has been already changed in current Github code. I was using the version from CRAN.

Thanks, yes I'll try to get the dev version submitted to CRAN this week.
