Скачать или смотреть R tutorial: Lattice tutorial, how to make a grouped bar chart, part 1

Here's my tutorial on how to make a lattice grouped bar chart, or bar plot. In this video, you'll learn how to make a grouped bar chart that shows the number of Prix de Lausanne ballet dances that were choreographed by men, and the number that were choreographed by women.

Steps:
1. Put your data into Excel into the right format. This is a bit tricky.
2. Import lattice into R
3. Import Excel table into R. You'll have to make it a comma separated value (csv). You can do it with read.csv or do it manually with read.table, like I did.
4. Set up the x, y, and and groups in the bar chart. Make sure to make horizontal = FALSE, or you'll get a horizontal bar chart.

Ta da! You have the core of a barchart. Next video, you'll learn how to make it look nice.

IDE: RStudio
Main packages: lattice
Main function: barchart
