Dear all,

  My machine is SUN Java Workstation 2100 with 2 AMD Opteron CPUs and 16GB RAM.   R is compiled as 64bit by using SUN compilers.   I trying to fit quantile smoothing on my data and I got an message as below.

> fit1<-rqss(z1~qss(cbind(x,y),lambda=la1),tau=t1)
Error in as.matrix.csr(diag(n)) : cannot allocate memory block of size 2496135168

  The lengths of vector x and y are both 17664.   I tried and found that the same command ran with x[1:16008] and y[1:16008].   So, it looks to me a memory related problem, but I'm not sure how I can allocate memory block.    I read the command line option but not sure what do to with it.    Could you help me on this?

Thank you very much,
