Treemaps in R

Following the directions from: http://flowingdata.com/2010/02/11/an-easy-way-to-make-a-treemap/

I learned:

• data <- read.csv("http://datasets.flowingdata.com/post-data.txt")install.packages("portfolio")
• library(portfolio)
• map.market(id=data$id, area=data$views, group=data$category, color=data$comments, main="FlowingData Map")

So basically, I learned how to read in data from the Flowing Data website, how to install (and re-install--> dev.off() ) packages, and then the Treemap tutorial worked. Pretty awesome. 

This is the longer version of what happened:

> map.market(id=data$id, area=data$views, group=data$category, color=data$comments, main="FlowingData Map")

Hit <Return> to see next plot: 

Error in .Call.graphics(C_palette2, .Call(C_palette2, NULL)) : 

  invalid graphics state

> dev.off()

> data <- read.csv("http://datasets.flowingdata.com/post-data.txt")

> install.packages("portfolio")

Error in install.packages : Updating loaded packages

> library(portfolio)

Now to edit a CSV file with data that is interesting.
