How can I embed a small data set into my R code? That was the question I came across today, when I prepared my talk about Dynamical Systems in R with simecol for the forthcoming Cologne R user group meeting.
I wanted to add all the R code of the talk to the last slide. That's easy, but the presentation makes use of a small data set of 3 columns and 21 rows. Surely there must be an elegant solution that I can embed the data into the R code, without writing x <- c(x1, x2,...).
Of course there is a solution, but let's look at the data first. It shows the numbers of trapped lynx and snowshoe hares recorded by the Hudson Bay company in North Canada from 1900 to 1920.
