Dear Mr Weylandt and R helpers,
Thanks a lot for your suggestion. Unfortunately the "return" statement in my
original R code returns me different results which are obtained after
processing the function I have constructed.
My requirement for storing the product-wise random numbers is just a part of my
whole exercise. For each of the products, I generate a set of random no.s,
process these, construct some statistics and obtain these statistics using the
"Return" statement. So for each of the products, I get these set of statistics
generated and that is not my problem.
My problem is "BESIDES getting my required output (which anyways I am
getting)", I need the product-wise random numbers I have already generated and
store them together in a single data.frame. So a single data.frame gives me all
the product wise random nos.
I am reproducing my problem once again -
# ____________________________________
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 = function(x)
my_code(product = x$product, output_avg = x$output_avg,
output_stdev = x$output_stdev))
There
are some 12 products (and this may vary each time). In my original
code, the "return" statement returns me some other output. Here for
simplicity sake, I am just using the values as given in input.
PROBLEM
I
want to store the random no.s (BUR_mc) as generated above for each of
the products and store them in a single data.frame. Now when I access
'sim_BUR.csv', I get the csv file where the random nos. generated for
the last product are getting stored. I need something like
product random no
product1 .......
product1
.......
.............................
product1 ....... # (There will be 100 such values for
product1)
product2 .......
product2 .......
............................
............................
product12 ......
............................
product12 .......
Thanking you in advance
Vincy
