Building a choropleth map of Italy using mapIT

R blog By January 20, 2015 Tags: , , , , 7 Comments

In the R environment, different packages to draw maps are available. I lost the count by now; surely, sp and ggmap deserve consideration. Despite the great availability of R functions dedicated to this topic, in the past, when I needed to draw a very basic map of Italy with regions marked with different colours (namely a choropleth map), I had a bit of difficulties.


The R user point-of-view about "Statistics Without the Agonizing Pain"

Contrary to general expectations, or at least to my expectations, the logical and analytical concepts behind statistics are rather difficult to understand by engineers. In general, despite their heavy background in maths and their above average fluency with computer programming, there seems to be a broken bridge with the statistical world and often they prefer to stay in the safe "math bank" of the river, despite the road to statistical fluency is shorter than they think.


R Package or Library

In these days, I was talking about an R package I developed with a colleague. He used several times the word library to refer to the R package. So, I realized that many R users do not know that package and library are not synonymous when referring to R.

The "Writing R Extensions" manual is clear: "A package is not a library", although the same manual admits "this is a persistent mis-usage".
