Last week I was invited to give an introduction to googleVis at Lancaster University. This time I decided to use the R package slidify for my talk. Slidify, like knitr, is built on Markdown and makes it very easy to create beautiful HTML5 presentations.
Introduction to googleVis Separating content from layout is always a good idea. Markup languages such as TeX/LaTeX or HTML are built on this principle.
After last week’s kerfuffle I hope the roll out of googleVis version 0.3.2 will be smooth. To test the water I release this version into the wild here and if it doesn’t get shot down in the next days, then I shall try to upload it to CRAN. I am mindful of the CRAN policy, so please get in touch or add comments below if you find any show stoppers.
The third Cologne R user meeting took place last Friday, 5 October 2012, at the Institute of Sociology.
The evening was sponsored by Revolution Analytics, who provided funding which went towards the Kölner R user group Meetup page. We had a good turn-out with 18 participants showing up and three talks by Dominik Liebl, Jonas Stein and Sarah Westrop. Photos: Günter Faes Dominik Liebl presented ideas of his forthcoming paper/vignette with Oualid Bada on Panel Data Analysis with Heterogeneous Time Trends.
Every year the UK’s general insurance actuarial community organises a big conference, which they call GIRO, short for General Insurance Research Organising committee.
This year’s conference is in Brussels from 18 - 21 September 2012. Despite the fact that Brussels is actually in Belgium the UK actuaries will travel all the way to enjoy good beer and great talks.
On Wednesday morning I will run a session on Using R in insurance.
Today I feel very lucky, as I have been invited to the Royal Statistical Society conference to give a tutorial on interactive web graphs with R and googleVis. I prepared my slides with RStudio, knitr, pandoc and slidy, similar to my Cambridge R talk. You can access the RSS slides online here and you find the original R-Markdown file on github. You will notice some HTML code in the file, which I had to use to overcome my knowledge gaps of Markdown or its limitations.
The next version of the googleVis package has been released on the project site and CRAN. This version provides updates to the package vignette and a new example for the gvisMerge function. The new sections of the vignette have been featured on this blog in more detail earlier: Using googleVis with knitr (Link to post) Using Rook with googleVis (Link to post) Using Reduce with gvisMerge to display several charts on a page (Link to post) Additionally two little bugs were fixed: Data frames with one row only were not displayed in a chart.
Tonight I will give a talk at the Cambridge R user group about googleVis. Following my good experience with knitr and RStudio to create interactive reports, I thought that I should try to create the slides in the same way as well.
Last Saturday I met the guys from RStudio at the R in Finance conference in Chicago. I was curious to find out what RStudio could offer. In the past I have used mostly Emacs + ESS for editing R files. Well, and what a surprise it was. JJ, Joe and Josh showed me a preview of version 0.96 of their software, which adds a close integration of Sweave and knitr to RStudio, helping to create dynamic web reports with the new R Markdown and R HTML formats more easily.
