[R] How to create a high-dimensional matrix

Hi, everyone I need to create a 429497 x 429497 matrix. When I use *matrix(0,429497,429497)* I got the error information : Error in matrix(0, 429497, 429497) : too many elements specified Then I use "ff" package, try to store this matrix on disk * x<-ff(0,dim=c(429497,429497)* And I got the err
