Before doing anything interesting in R, we need to have some data to play with. I want to read in a list of End of Day prices for a company, and working out the average volume of that share traded.
This solution is going to require an account on www.eoddata.com to get access to the historical close prices of a share.
I’ve downloaded the close prices for Tesco and placed them in /users/nick/rdata
This is the code to read in the text file and calculate the average volume of shares traded:
> setwd(‘/users/nick/rdata’) # set the working directory
> df <- read.csv(‘tesco.txt’)
