I download a R markdown template. And at the beginning of .rmd file, it has such codes:
# Setup package dir my.package.dir <- "[dir to package folder]" # Define directories my.dir <- "/Users/zhaoyao/Documents/AAE 772/hw3" hw.dir <- "/Users/zhaoyao/Documents/AAE 772" # Set directory setwd(my.dir)
What does this mean? What should I put in brackets? What's the differences among these three dir? I put my data set in the my.dir. Is this correct?
