[R] Data Simulation

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 rmvnor

[R] Data simulation for ANOVA decomposition into sums of squares

Dear listserv, Please consider the following dataset: x <- matrix(nrow = 8, ncol = 2) colnames(matrix) <- c("classification", "soluble_fiber") x[1:4,1] <- "bagel" x[5:8,1] <- "donut" How would I simulate a dataset for a one-way fixed-effect ANOVA (where "classification" is the treatment variabl
