Solution in the R language to project Euler Problem 15. The problem asks to calculate the number of pathways through a 20 by 20 grid. Continue reading → The post Euler Problem 15: Pathways Through a Lattice appeared first on The Devil is in the Data.

Lattice exercises – part 2

May 24, 2016
By

In this set of exercises we will use lattice package. Firstly, we have to install this package with command install.packages("lattice") and then we will call it library(lattice) . Lattice package permits us to create univariate, bivariate and trivariate plots. For this set of exercises we will see trivariate plots. We will use a dataset example

How to place titles in lattice plots

June 16, 2015

I like the Economist theme in the latticeExtra package. It produces nice looking charts that mimic the design of the weekly newspaper, such as in this example:For some time I wondered how I could put the title of my lattice plots into the top left corner as well (by default titles are centred). Reviewing...

Combining several lattice charts into one

April 21, 2015

Last week I mentioned the grid.arrange function of the gridExtra package that allows me to combine graphical grid objects onto one page. The latticeExtra package provides another elegant solution for trellis (lattice) plots: the function c.trellis() or...

Originally posted on Learning R: The data visualization package lattice is part of the base R distribution, and like ggplot2 is built on Grid graphics engine. Deepayan Sarkar’s (the developer of lattice) book Lattice: Multivariate Data Visualization with R gives a detailed overview of how the package works. All the figures and code used to…

Adding labels within lattice panels by group

February 18, 2014
By

The other day I had data that showed the development of many products over time. I grouped the products into categories and visualised the data as line graphs in lattice. But instead of adding an extensive legend to the plot I wanted to add labels to each line's latest point. How do you do that? It turns out that...

Conditioning and Grouping with Lattice Graphics

February 17, 2014
By

Conditioning and grouping are two important concepts in graphing that allow us to rapidly refine our understanding of data under consideration. Conditioning, in particular, allows us to view relationships across “panels” with common scales. Each panel contains a plot whose data is “conditional” upon records drawn from the category that supports that particular panel (an
