R Memory problem with Panelvar package

Hi everyone, I am a new user of R. I have been having problems running the 'pvargmm' function from the package PanelVar for several weeks now. It is a small code, but so far I've only been able to use it for a tiny dataset. I even tried running it on a virtual machine but I always get errors related to insufficient memory, such as "cannot allocate vector of size...", or "cholmod error 'out of memory' ..." My dataset contains 2784 observations, population 48, 58 years and 4 variables. Could you please help me with some solutions?
