Hi,

My name is Maria del Carmen Romero and I was working with package snow until
December, 2010 without problems. Now, when I try to create 2 clusters
(because I have a dual-core processor) with the instruction:
> cl<-makeCluster(2,type="SOCK")

I have to different problems:

- In earlier versions to 2.13, the error is:
Error en socketConnection(host, port, open = "a+b", blocking = TRUE) :
  argumento 'port' inválido
Además: Warning message:
In socketConnection(host, port, open = "a+b", blocking = TRUE) :
  NAs introducidos por coerción

- In the version to 2.13, the program hangs and I have to hit Ctrl-C.

I obtain the same error in case I try to execute the instruction
makeSOCKcluster. I also probe the instructions:
cl <- makeSOCKcluster(c("localhost", "localhost")) and specifying the IP
number,
but the problems are the same.

I try to "debug" the instruction and I think that the problem appears when
it try to establish the class for the cluster created.

I appreciate very much if someone can help me.
Thanks,
María
