I am just fitting a simple linear regression model.  The documentation is far from clear what the FLXmclust function does, but, it in principle could do all I need, however, I do not get sentible results as if I try the following the result is poor:
>> x<-c()
>> for(i in 0:99){x$y[2*i]=(0+i);x$x[2*i]=i;x$x[2*i+1]=i;x$y[2*i+1]=i+1000;x$g[2*i]=1;x$g[2*i+1]=2}
>> m1<-flexmix(y~x  ,data=x,k=2)
>> table(x$g,m1 at cluster)
