[R] Data Simulation

[ycyi121]

Hi,

I have great difficulty in simulation the a dataset based in a loading
matrix [c(1,1,1,2,3,3,3,4,4,3,2,2,1,1), 7, 2) and an error covariance matrix
is 2*I. I have to simulate a dataset with 7 variables and 50 rows. I search
a lot and did find some information on this, for example, using rmvnorm().
But I could do it.

Please help!
