Hello:

My problem is that I have a data frame of means, and a data frame of standard deviations which match up to each mean.  I have been trying to create 500 random numbers in a given dataset for each mean/sd combination, but I am only able to generate the last value in each data set to create one dataset (there should be 28 in all).  Examining my code, what can I change to generate 28 datasets based on respective mean and sds?

a1<-c(178.07,178.28,178.08,177.74,177.04,178.17,177.58,57.71,59.6,60.92,59.48,59.32,61.59,59.94,28.9,29.82,30.73,25.68,27.93,28.98,29.76,123.48,127.27,127.8,127.2,127.13,126.71,125.5)
a2<-c(1.69,1.3,1,.18,1.53,1.31,1.35,1.83,1.56,1.12,.74,1.48,1.67,1.53,.95,.87,0.03,1.12,1.95,1.22,1.04,1.64,1.83,1,1,1.08,1.35,2.37)
for(i in 1:length(a1))
    for(j in 1:length(a2))
        x<-rnorm(500,mean=a1[i],sd=a2[j])

Thank you,

Agl
