Edit: actually I managed to click through to find this screenshot: http://fasterstat.com/Images/Desktop/12_R_gui.png which looks novel (can't currently watch the video unfortunately)
Recommendation for the developer (if you're not doing this already): market hard to finance businesses. You'll make a killing.
Personally I would NOT want to have anyone use R with a spreadsheet program.
1) I want manipulated data that is clear to replicate
2) I want my output to be plots and reports not another spreadsheet
Knitr for the win! Seriously great package (and integrated nicely into R Studio), I use it for all my reports, presentations, etc...
- Works with just about any language you can imagine, not just R or the few other hypothetically supported languages
- Allows me to write in a lightweight Markdown-comparable, LaTeX-augmentable syntax, except org-mode supports internal references.
- Lets you do truly obscene things like pass values from bash, to python, to julia, to R
As Emacs begins to move more and more to Guile, I hope that the org-* functionality can be instrumented as embeddable libraries. I understand that Emacs isn't for everyone, and thus I wish org-mode (the format) and org-babel were available to the rest of the world. I was surprised to find how few edge-cases aren't better handled by org-* than knitr / RMarkdown.
R and Excel integration already exists: http://www.r-bloggers.com/a-million-ways-to-connect-r-and-ex...
Not that I think it's a good idea. Also, R is already a thing in Finance, quite a few job postings list it as a useful skill, and Linkedin has R/Finance groups.
Anyhow, it's much easier to manipulate data with scripts than spreadsheets, especially with R packages like quantmod. Looking at giant spreadsheets makes my eyes bleed and my head hurt, plus I think R Studio makes more sense for newbies to R anyway (and R Studio Server is fantastic for businesses).

There is also inconsistent use of 'Addin' and 'Add-In'.
It was hard/impossible for me to read the R code in the video while playing it at 1080p.
