y2 --> y1 This function is used to transform the break points of the first y axis to the values of the second y axis. Note that the axis are swapped now. transformation function: f (y1) = 40*x - 110. Plotting. Note how the transformation functions are used in the ggplot call to transform the data "on-the-fly". By default, ggplot2 creates a histogram with 30 bins. That’s often fine, but sometimes, you want to increase or decrease the number of bins. To do that, we can use the bins parameter. Here, we’ll decrease the number of bins to 10 bins: ggplot (data = txhousing, aes (x = median)) + geom_histogram (bins = 10) OUT: Create a scatter plot using ggplot () and visualize the cars dataset with the car’s stopping distance dist on the x-axis and the speed of the car on the y-axis. The ggplot2 package is already loaded. Follow these steps to create the plot: Specify the dataset through the ggplot () function. Specify a geometric point layer with the geom_point You can quickly add vertical lines to ggplot2 plots using the geom_vline () function, which uses the following syntax: xintercept: Location to add line on the x-intercept. This can be one value or multiple values. linetype: Line style. Default is ‘solid’ but you can specify ‘twodash’, ‘longdash’, ‘dotted’, ‘dotdash Part of R Language Collective. 2. I want to alter a ggplot2 plot in R using the ggplot_build and ggplot_gtable functions and use it afterwards in a plot_grid. Example code to make the plot: library (ggplot2) library (cowplot) p1 . 246 216 55 319 336 243 339 92
