Bar charts in ggplot2
# geom_bar is designed to make it easy to create bar charts that show # counts (or sums of weights) g <-ggplot (mpg, aes (class)) # Number of cars in each class: g + geom_bar () # Total engine displacement of each class g + geom_bar ( aes ( weight = displ )) Bar and line graphs (ggplot2) Problem; Solution. Basic graphs with discrete x-axis. Bar graphs of values; Bar graphs of counts; Line graphs; Graphs with more variables. Bar graphs; Line graphs; Finished examples; With a numeric x-axis. With x-axis treated as continuous; With x-axis treated as categorical; Problem. You want to do make basic bar or line graphs. Solution To make a bar chart with ggplot2 in R, you use the geom_bar() function. However, note that the default stat is stat_bin(), which is used to cut your data into bins. Thus, the default behavior of geom_bar() is to create a histogram. Barplot of counts. In the R code above, we used the argument stat = “identity” to make barplots. Note that, the default value of the argument stat is “bin”.In this case, the height of the bar represents the count of cases in each category.
