So, the FIFA World Cup is over. Germany won. Yay!Want to share your content on R-bloggers? click here if you have a blog, or here if you don't.
Now with so much less football matches to watch, I tried the awesome new R package rCharts by Ramnath Vaidyanathan. In this case, I used the capability to generate NVD3 charts. Check it out…
You can mouse over the data points (players) to get the name of the player and information about how many of his shots were on target. You can switch on/off all countries and magnify portions of the plot by moving your mouse around (activate the option ‘magnify’ to do so).
The code is really simple (that’s why rCharts is so awesome). The tooltips, however, took me a while. I only supplied the code to generate the chart. I suppose you have a dataframe shots that looks like this:
name country games minutes shots shots_goal shots_alu
1 Karim BENZEMA fra 5 450 32 25 1
2 Angel DI MARIA arg 5 423 25 21 1
3 CRISTIANO RONALDO por 3 270 23 14 1
4 Lionel MESSI arg 7 693 22 10 0
5 Xherdan SHAQIRI sui 4 387 21 16 0
6 Arjen ROBBEN ned 7 690 20 19 0

library(rCharts)
pl <- nPlot(x = "minutes", y = "shots", data = shots, group = "country", type = "scatterChart")
pl$params$width <- 600
pl$params$height <- 600
pl$xAxis(axisLabel = ‘Minutes played’)
pl$yAxis(axisLabel = ‘Shots’)
pl$chart(tooltipContent = “#! function (a, b, c, data) {
return data.point.name + ‘, ‘ + data.point.shots_goal + ‘ shots on goal.’
} !#”)
pl$save(“fifa.html”, standalone=T)
