This is an R Markdown document. Markdown is a simple formatting syntax for authoring HTML, PDF, and MS Word documents. For more details on using R Markdown see http://rmarkdown.rstudio.com.

When you click the Knit button a document will be generated that includes both content as well as the output of any embedded R code chunks within the document. You can embed an R code chunk like this:

library(googleVis)
## Creating a generic function for 'toJSON' from package 'jsonlite' in package 'googleVis'
## 
## Welcome to googleVis version 0.6.0
## 
## Please read the Google API Terms of Use
## before you start using the package:
## https://developers.google.com/terms/
## 
## Note, the plot method of googleVis will by default use
## the standard browser to display its output.
## 
## See the googleVis package vignettes for more details,
## or visit http://github.com/mages/googleVis.

                        strip.white = TRUE,

DengueStates <- gvisGeoChart(DengueIndia, "States", "Denguecase", options=list(region="IN", displayMode="regions", resolution="provinces"))

You can also embed plots, for example:

print(DengueStates, 'chart') ## same as cat(sc$html$chart)

Note that the echo = FALSE parameter was added to the code chunk to prevent printing of the R code that generated the plot.
