Using nproc - Githubissues

I just noticed that the nproc argument is not working for me.

The example hlme works

m1<-hlme(Y~Time*X1,random=~Time,subject='ID',ng=1,data=data_hlme)

But this does not

cl <- parallel::makeCluster(10, "PSOCK")
m1<-hlme(Y~Time*X1,random=~Time,subject='ID',ng=1,data=data_hlme, nproc = cl, clustertype = "PSOCK")
# Error in mla(b = b, m = length(b), fn = loglikhlme, clustertype = clustertype,  : 
#   'list' object cannot be coerced to type 'double'

How can I solve or avoid this error?
