In stephlocke/Rtraining: Training Materials on R

Step 1: Google "What is R?"

I Google frantically and find out...

• R (birthed out of S) has been around for ages
• Has massively increased in popularity
• Lots of big players like SAP, TIBCO, and Oracle have implemented it
• Microsoft are catching up quick!
• It's statistician heaven
• It produces very pretty charts
• Huh, you can make XKCD cartoons in it?

Eep, but I'm not a stats bod or a programmer, what will I do? Do my usual stuff, but swisher!

Step 2: Get R installed

OK, I need to get this thing called R installed on my laptop!

• Install R from r-project.org myself
• Jump on IT's desk until they install Rstudio via Rstudio.com for me
• Use R to nab some useful packages

Step 7: Produce presentation

I need a slide deck for the boss to take use!

• Use rmarkdown to produce SamplePresentation.Rmd
• Really light syntax, same as Stack Overflow
• Customisable via CSS
• Create slides (html or PDF) or docs (html, PDF, Word)
• Use a modular design
• Re-knit to get latest data

Phew, he's got something to show to the Board & a web page he can play with all day long.

We learnt along the way:

• connect to our data using RODBC
• manipulate it with data.table
• chart it with ggplot2
• make documents with rmarkdown
• produce interactive reports using shiny

Not bad for a day's work!
