Open homePrices.R and use the compile HTML notebook feature. You'll see it's really easy to compile this and get an HTML document. Open your other scripts and test it out there as well.
Typically when sharing your work, it's nice to include at the bottom of your script the results of sessionInfo() so that others can see what version of R you used and other relevant information (see below). Add this to one of your R scripts and re-compile the notebook.
Since this is just an HTML file, you can easily share this document over the web or on an internal coporate server. Graphics are 64-bit encoded into the file so that it can be easily shared with others. You don't need to attach any other image files! This makes it easy to publish the document for others to view in a standard web browser.
