Upload .html file

Dear Guil Hernandez, I write you because I am developing R-tutorials [R is a statistical language] for teaching purposes which I intend to display on my personal website. With R, using RStudio and knitr, I am able to produce .html files, containing statistical analysis and displaying figures, etc. Unfortunately, I cannot just upload it to my website. The reason for this is that squarespace.com [where my personal website is hosted/built] does not support this feature. The only solution I found is to somehow upload the .html files somewhere and then use iframe to link it my website. So I have been researching for solutions for a while now, and it seemed that Jekyll and GitHub were viable solutions. However, in this course, you teach to make posts in markdown, whose format are .md, which is used by Jekyll to make a html. For me, that is not a viable solution, as the .html file produced has intricate format which Jekyll cannot handle and it messes up tables and other aspects badly. Do you have any suggestions on how to use this course and what I learned from it to achieve my goals with GitHub and Jekyll? Or do you have an alternative way to do this? Any feedback is appreciated :) Thank you very much for you time and work. Flavio
