A lightning talk tour of why `mgcv` is awesome, including what regression models are, options for dealing with non-linear relationships, what splines are, and how we can use splines in a Generalized Additive Modle (GAM). Simon Wood's excellent `mgcv` package makes this easy to build and fit.
Getting data into R One of the things I found most difficult when learning R was getting data from our SQL Servers into R to analyse. It is easy to load csv files, or pull example datasets from packages, but a little more knowledge is required to connect to external databases. I think this is a common problem for my NHS colleagues when learning R and probably for others too.
