Data Visualization cheatsheet, plus Spanish translations

RStudio Blog

data visualization cheatsheet

We’ve added a new cheatsheet to our collection. Data Visualization with ggplot2 describes how to build a plot with ggplot2 and the grammar of graphics. You will find helpful reminders of how to use:

  • geoms
  • stats
  • scales
  • coordinate systems
  • facets
  • position adjustments
  • legends, and
  • themes

The cheatsheet also documents tips on zooming.

Download the cheatsheet here.

Bonus – Frans van Dunné of Innovate Online has provided Spanish translations of the Data Wrangling, R Markdown, Shiny, and Package Development cheatsheets. Download them at the bottom of the cheatsheet gallery.

tidyr 0.2.0 (and reshape2 1.4.1)

RStudio Blog

tidyr 0.2.0 is now available on CRAN. tidyr makes it easy to “tidy” your data, storing it in a consistent form so that it’s easy to manipulate, visualise and model. Tidy data has variables in columns and observations in rows, and is described in more detail in the tidy data vignette. Install tidyr with:

install.packages("tidyr")

There are three important additions to tidyr 0.2.0:

  • expand() is a wrapper around expand.grid() that allows you to generate all possible combinations of two or more variables. In conjunction with dplyr::left_join(), this makes it easy to fill in missing rows of data.
    sales <- dplyr::data_frame( year = rep(c(2012, 2013), c(4, 2)), quarter = c(1, 2, 3, 4, 2, 3), sales = sample(6) * 100 ) # Missing sales data for 2013 Q1 & Q4 sales #> Source: local data frame [6 x 3] #> #> year quarter sales #> 1 2012 1 400 #>…

Introducing ggvis

RStudio Blog

Our first public release of ggvis, version 0.3, is now available on CRAN. What is ggvis? It’s a new package for data visualization. Like ggplot2, it is built on concepts from the grammar of graphics, but it also adds interactivity, a new data pipeline, and it renders in a web browser. Our goal is to make an interface that’s flexible, so that you can compose new kinds of visualizations, yet simple, so that it’s accessible to all R users.

Update: there was an issue affecting interactive plots in version 0.3. Version 0.3.0.1 fixes the issue. The updated source package is now on CRAN, and Windows and Mac binary packages will be available shortly.

ggvis_movies

ggvis integrates with Shiny, so you can use dynamic, interactive ggvis graphics in Shiny applications. We hope that the combination of ggvis and Shiny will make it easy for you to create applications for interactive data exploration and…
