googleVis code development moved to GitHub

After nearly 4 years of developing googleVis on Google Code with SVN we decided to move to GitHub. The main reason was that Google stopped the facility of hosting pre-CRAN builds of the package for user testing. The devtools package on the other hand makes it really easy to install packages from source hosted on GitHub. Additionally, we hope that GitHub will make collaboration with others more effective. Thus, bookmark http://github.com/mages/googleVis.

Screen shot of some of the new features in googleVis 0.5.0-1.

There are some exciting new features in the development version of 0.5.0-1 of googleVis, reflecting the enhanced Google Chart Tools API:

New Features

• New functions gvisSankey, gvisAnnotationChart, gvisHistogram, gvisCalendar and gvisTimeline to support the new Google charts of the same names (without 'gvis').
  
• New demo Trendlines showing how trend-lines can be added to Scatter-, Bar-, Column-, and Line Charts.
  
• New demo Roles showing how different column roles can be used in core charts to highlight data.
  
• New vignettes written in R Markdown showcasing googleVis examples and how the package works with knitr.

Changes

• The help files of gvis charts no longer show all their options, instead a link to the online Google API documentation is given.
  
• All googleVis output will be displayed in your default browser. In previous versions of googleVis output could also be displayed in the preview pane of RStudio. This feature is no longer available with the current version of RStudio, but is likely to be introduced again with the release of RStudio version 0.99 or higher.
  

I will post about the new features and changes in the coming weeks. Please feel free to test the development version already. Visit our GitHub project page for installation instructions and further details.

For the impatient (you will require R >= 3.0.2):

install.packages(c("devtools","RJSONIO", "knitr", "shiny", "httpuv"))
library(devtools)
install_github("mages/googleVis")

The registration for the second conference on R in Insurance on Monday 14 July 2014 at Cass Business School in London has opened.

This one-day conference will focus again on applications in insurance and actuarial science that use R, the lingua franca for statistical computation. Topics covered may include actuarial statistics, capital modelling, pricing, reserving, reinsurance and extreme events, portfolio allocation, advanced risk tools, high-performance computing, econometrics and more. All topics will be discussed within the context of using R as a primary tool for insurance risk management, analysis and modelling.

The intended audience of the conference includes both academics and practitioners who are active or interested in the applications of R in insurance.

Invited talks will be given by:

• Arthur Charpentier, D�partement de math�matiques Universit� du Qu�bec � Montr�al
• Montserrat Guillen, Dept. Econometrics University of Barcelona together with Leo Guelman, Royal Bank of Canada (RBC Insurance division)

Attendance of the whole conference is the equivalent of 6.5 hours of CPD for members of the Actuarial Profession.

We invite you to submit a one-page abstract for consideration. Both academic and practitioner proposals related to R are encouraged. The submission deadline for abstracts is 28 March 2014.

Details about the registration and abstract submission are given on the dedicated R in Insurance page at Cass Business School.

googleVis 0.4.7 with RStudio integration on CRAN

In my previous post, I presented a preview version of googleVis that provided an integration with RStudio's Viewer pane (introduced with version 0.98.441).

Over 80% in my little survey favoured the new default output mechanism of googleVis within RStudio. Hence, I uploaded googleVis 0.4.7 on CRAN over the weekend.

However, there were also some thoughtful comments, which suggested that the RStudio Viewer pane is not always the best option. Indeed, Flash charts and gvisMerge output will still be displayed in your default browser, but also if you work on larger charts and with smaller screen, then the browser might still be the better option compared to the Viewer pane - of course you can launch the browser from the Viewer pane as well.

Hence, googleVis gained a new option 'googleVis.viewer' that controls the default output of the googleVis plot method. On package load it is set to getOption("viewer") and if you use RStudio, then its viewer pane will be used for displaying non-Flash and un-merged charts. You can set options("googleVis.viewer" = NULL) and the googleVis plot function will open all output in the default browser again. Thanks to J.J. from RStudio for the tip.

The screen shot below shows a geo chart within the RStudio Viewer pane of the
devastating typhoon track of Haiyan that hit Southeast Asia last week.

Display googleVis charts within RStudio

The preview version 0.98.441 of RStudio introduced a new viewer pane to render local web content and with that it allows me to display googleVis charts within RStudio rather than in a separate browser window.

I think this is a rather nice feature and hence I have updated the plot method in googleVis to use the RStudio viewer pane as the default output. If you use another editor, or if the plot is using one of the Flash based charts, then the browser is still the default display.

The behaviour can also be controlled via the option viewer. Set options("viewer"=NULL) and googleVis will plot all output in the browser again.

Of course shiny apps can also run in the viewer pane. Here is the example of the renderGvis help page of googleVis. For more information about the new viewer pane see the online RStudio documentation.

For the time being you can get the next version 0.4.6 of googleVis from our project site only. Please get in touch if you find any issues or bugs with this version, or add them to our issues list.
