Download & Install Instructions for the submitted MovieLens Project Folder/Files in R:

• In your web browser enter the following URL into the address bar: https://github.com/jpoconnor1961/MovieLens10M
• In the github MovieLens10M repository, click on the green button that says "Code", and then click on the "Download ZIP" choice in the dropdown menu.
• In your FileManager, extract the zip folder "MovieLens10M-main" that was downloaded. This will create a new "MovieLens10M-main" folder that will contain another nested "MovieLens10M-main" folder that will contain a "harvard_oconnor_movie" folder which contains all of the project files.
• In your FileManager, Copy or Move the "harvard_oconnor_movie" folder (which contains all of the project files) to the Project folder for your R application.
• In your R application, select "New Project" and then select an "Existing Directory". Next, browse/navigate to the "harvard_oconnor_movie" folder to select that as the working directory, and then select the "Create Project" button at the bottom-right-side of the wizard dialog box.
• The "harvard_oconnor_movie" working directory folder in your R application will contain the following:
  • harvard_oconnor_movie_PDF file
  • harvard_oconnor_movie_Rcode file
  • harvard_oconnor_movie_RMD markdown file
  • 18 PNG image files to support the figures coded in the markdown file
  • ref.bibtex file that supports the markdown file
• If you have problems with "Knit to PDF" from the open markdown file tab, you may need to install or update your LaTeX package. In your R application, install the R package "tinytex" to make sure it is up to date (this is a LaTeX management package, not LaTeX itself). Open the tinytex package in R and run the install_tinytex() function (with the default settings) which installs LaTeX itself from a repository. After the LaTeX install, re-try to Knit to PDF again and the (still open) tinytex R package should kickin during the knitting process and help R to render the PDF by automatically installing any missing LaTeX packages or files. Depending on the scope of the original LaTeX problem, it may take a few re-trys of Knit to PDF for the tinytex manager to find and correct all of the missing packages, files, paths, etc.
