ggplot2 is one of the most elegant R packages for data analysis and visualization. Recently I gave a tutorial on ggplot2 package. You could find my ggplot2 notes here (click the image below).

You could find my presentation below. The presentation made in html5. Use your left/right key to go through the presentation.

Hi Vinu,

Nice notes and presentation!

Look forward for more such R-related resources from you!

Btw, the other day I was trying to work on detecting structural change in a time-series using strucchange package of R, and I couldn’t find it. Would be thankful to you if you could help me out!

Hi Vinu,

Nice post.

In my project sometimes I need to highlight certain location of a country by its longitude & latitude. Say for example I need to highlight stores of Romania based on their performance measured in 1-3 point scale with 3 different colors & I have the longitude & latitude for those stores.

Can you please suggest me some links where I can get an idea about how to do such things using R?

Thanks,

Niladri

Hi Niladri,

You can check the pdf file in the blog. I have provided the R codes for Maps demonstraton. Graphics using maps are polygon in XY cordinates. So you could easily map the longitude and lattitude. My suggestion would be check maps package in R and Stackoverlow questions. Or write to me.

Thanks Vinu. Surely I will look into the pdf
