Question

Below is the code in a .r file. I want to execute this from a Windows command prompt, but how?

library(coda)
a <- read.coda("CODAchain1.txt","CODAindex.txt")
out <- capture.output(summary(a)) 
cat(out,file="out.txt",sep="\n",append=FALSE) 

Answer 1

You can make a text file named coda_scrp.r and then at the command prompt type:

R CMD BATCH /<full-path>/coda_scrp.r
