Hans Rosling's Gapminder: Let Your Data Dance!

Paket googleVis boleh disebut sebagai "turunan" dari Gapminder karya Hans Rosling. "Let your data dance," begitu kata profesor dalam bidang kedokteran dan statistika ini. Ide Rosling adalah membuat visualisasi data secara interaktif sehingga kita mendapatkan pengertian hubungan antar variabel.


Software Gapminder dapat diunduh dari www.gapminder.org


knitr (R package)

Saya terkagum-kagum dengan kemampuan knitr (dan paket-paket penunjangnya) dan RStudio dalam menulis dokumen. Ini baru namanya sekali tepuk banyak lalat!
Fitur-fitur yang keren, antara lain

  • integrasi R output dengan LaTeX (yg sering bikin nangis bombay)
  • integrasi R output ke dokumen HTML
  • fasilitas eksternalisasi untuk modularitas

Informasi lebih lanjut dapat dibaca di Deskripsi paket knitr di CRAN dan Pengarang paket knitr.

googleVis Example from Takahashi Blog

Source code of Google Motion Chart is taken from Takahashi's Blog.
The chart is produced by these simple 3 lines:

M1 <- gvisMotionChart(Fruits, idvar="Fruit", timevar="Year")
print(M1)
#or
M1$html$chart

Data: Fruits, Chart ID: MotionChart_2011-01-10-21-41-52
R version 2.12.1 (2010-12-16), Google Terms of Use
