Population of Ireland on a 3d scatter plot

Image
The Central Statistics Office in Ireland has published this dataset: http://www.cso.ie/en/census/census2011griddataset/ And here is the user guide: http://www.cso.ie/en/media/csoie/census/documents/census2011griddataset/1,Km%C2%B2,Grid,dataset,User,Guide,2011.pdf It gives the population of each 1km square of Ireland on census night 2011. It has various buckets, but I have just looked at total population. I used the 3dscatterplot package in R which is very easy to use.  Here is my code: cen<-read.csv("COP2011_Grid_ITM_IE_1Km.csv") install.packages('scatterplot3d') library(scatterplot3d) scatterplot3d(cen$CENT_EAST, cen$CENT_NORTH, cen$TOT_P) and here is the resulting plot You can see the big cities jumping up there. It needs a lot of polish to avoid things like Cork getting swamped in the 3d projection, but that's it for now. 

Using R to analyse data from the Central Statistics Office in Ireland

I started a Coursera course this week called Getting and cleaning data . I was looking at some data from the CSO and realised that I needed to clean it up. The course is good, but quite difficult. It assumes you have not forgotten everything you learned in the previous course, R Programming.    Mid way through week 2 (I am playing a bit of catchup) I stumbled across this package http://pxr.r-forge.r-project.org/ px is the format that the CSO releases its 'raw' data in. This package puts that into a data frame which is more amenable to analysis. I reckon there has to be something lurking within the CSO dataset which is one of my main motivations for getting up to speed on R.  Nothing to declare yet, but hopefully I will find something interesting soon :)
