[R] [R-pkgs] Update: googleVis 0.2.4 - Using the Google Visualisation API with R

[Markus Gesmann]

Hi all,

Version 0.2.4 of the googVis package has been released on CRAN and 
will be available from your local CRAN mirror soon. 

googleVis provides an interface between R and the Google Visualisation API. 
The functions of the package allow users to visualise data stored in R with the 
Google Visualisation API without  uploading their data to Google

Since the last version a lot of work has been carried out under the bonnet to make 
googleVis  more flexible and easier to use. 

The new version no longer requires to install the package into a folder with access 
rights and  provides a better interface to insert the visualisation output into your 
own  sites.

For more information see:

And here are the NEWS:

Version 0.2.4 [2011-02-07]
==========================

Changes
   
   o plot.gvis no longer writes into the package folder. Instead
     temporary files are created. This overcomes the need to install
     the package into a directory with write access. Many thanks to
     Ben Bolker for this suggestion and code contribution.  
  
   o plot.gvis no longer requires the web server provided by
     the R.rsp package to display the visualisation output. Instead it
     uses the internal R HTTP help server. Many thanks to John Verzani
     for this suggestion and code contribution. 
  
   o R >= 2.11.0 is required to plot googleVis output, as it uses the
     internal R HTTP help server.
  
   o Updated vignette with a section on how to use googleVis with
     RApache and brew

NEW FEATURES

   o The plot function generates a web page which includes a link
     to the HTML code of the chart. Many thanks to Henrik Bengtsson
     for this suggestion.

   o gvis visualisation functions have a new argument 'chart id', to
     set the chart id of the exhibit manually.           

   o gvis functions return more details about the visualisation chart
     in a structured way. Suppose x is a 'gvis' object, than
     x$html$chart is a named character vector of the chart's
     JavaScript building blocks and html tags. 

   o print.gvis has a new argument 'tag', which gives the user more
     control over the output

   o New brew example files in: 
     system.file("brew", package = "googleVis")  

BUG FIXES

   o gvisTable did not accept datetime columns.
