For those starting out with spatial data in R, Robin Lo

This course is about getting to grips with the basics of the R command line for basic data analysis and visualisation. There's a focus on maps and ggplot2. The first part of the course uses Rich Harris's "Short Introduction to R" (here). The second part works through an "Introduction to Spatial Data and ggplot2" (Cheshire and Lovelace, 2013), which can be found...

The following is the code from a presentation made by Rosemary Hartman to the Davis R Users’ Group. I’ve run the code through the spin function in knitr to produce this post. Download the script to walk through here. First, make your plot. I am going to use the data already in R about sleep habits...

In this post, I use a simulated dataset (7 variables -3 factor and 4 numeric - and a sample size of 50) to create graphs/charts using base R, and replicate them using ggplot2, and rCharts. This is not an attempt to create an exhaustive database of grap...

The rather new-born Budapest Users of R Network, the only Hungarian R User Group so far, with already 85+ members, continues its really young traditions to have talks on data visualization and providing a place for Hungarian R users to socialize while having some free pizza and drinks.Our next session will focus on...

I have a standard code for ggplot2 which I use to make line graphs, scatter plots, and histograms. For lines or scatters: p<- ggplot(x, aes(x=Year, y=Rank, colour=Uni, group=Uni)) #colour lines by variable Uni #group Uni labelled variables in the same line Then: p + #you get an error if not for this step geom_line(size=1.2) +
