How do I generate one vector for every row of a data frame?
I am trying to generate a set of data points from a Gaussian mixture
model. My mixture model is represented by a data frame that looks

4 0.1 5 0.3
I have written the following function that generates the appropriate data:
gmm_data <- function(n, gmm) {
c(rnorm(n*gmm[1,]$weight, gmm[1,]$mean,
