Regex Problem in R

Chess tournament results are below where the information has some structure. Your job is to upload this data to github, and create an R Markdown file that links to the github data, and generate a comma delimited .CSV file with the following information for all of the players:

Players Name, Players State, Total Number of Points, Players Pre-Rating, and Average Pre-Rating of Opponents

For the first player, the information would be: Gary Hua, ON, 6.0, 1794, 1605

1605 was calculated by using the pre-tournament opponents ratings of 1436, 1563, 1600, 1610, 1649, 1663, 1716, and dividing by the total number of games played.

Note: Regular expressions are required to mine the data, so please have experience with these before attempting a solution.
