You need a greater allocation of RAM / 'memory'. If you cannot allocate more RAM, try to reduce the input number of variables by removing low expressed genes and those with low variance.

Edit: your very first command could be due to another issue. Try to simply restart your computer in order to clear your cache. When you start a new analysis in R, always start a new R session.
