Generation of random numbers in a function - (Return command)
...the respective mean and standard deviation.   My R code is as follows.   library(plyr) library(reshape2)   filtered_new <- data.frame(product_name = c("P1", "P2", "P3", "P4", "P5"), output_avg = c(22.71078,22.16979,21.34420,20.17421,19.83799), output_stdev = c(23.59924,21.21430,22.01025,18.88877,18.80436)) n <- 100 myfunction_mc = function(product_name, output_avg, output_stdev) { product_usage_borrowing_room_mc = rnorm(n, output_avg, output_stdev) output_avg_mc = mean(product_usage_borrowing_room_mc) output_stdev_mc = sd(product_usage_borro...

How to append the random no.s for different variables in the same data.frame
...ogize if I have not put forward my following query properly, though I have tried to do so.) Following is a curtailed part of my R - code where I am trying to generate say 100 random no.s for each of the products under consideration. library(plyr) n = 100 my_code = function(product, output_avg, output_stdev)     { BUR_mc = rnorm(n, output_avg, output_stdev) sim_BUR = data.frame(product, BUR_mc) write.csv(data.frame(sim_BUR), 'sim_BUR.csv', row.names = FALSE)   return(list(output_avg, output_stdev))     } result <- dlply(.data = My_data, .variables = "product", .fun = funct...
