In addition, if you set the argument back.to.back as FALSE, the plots won’t be displayed back-to-back: (data, data2, back.to. Other interesting function of the aplpack package is that allows you to compare two stem and leaf plots with the function, that by default plots a back-to-back (two sided) stem and leaf display: # install.packages("aplpack") stem(data, scale = 3) The decimal point is 1 digit(s) to the right of the |Ĭomparative (back to back) stem and leaf diagram in R In this example, the first of the duplicated stem shows the leafs corresponding to values lower than 5 and the second the leafs corresponding to values equal or higher to 5. Note that if you set scale = 3, each stem will be duplicated. In order to solve this issue you can change the height of the plot with the scale argument as follows: stem(data, scale = 2) The decimal point is 1 digit(s) to the right of the | This is due to the stems are grouped (the first stem is for 0 and 1, the second for 2 and 3, and so on). Stem And Leaf Plot Rules: Following rules must be considered if you want to create stem and leaf plot: Look For The Smallest And Largest Values: First of all, you need to figure out the smallest and biggest figures that are present in the data set. However, you may have noticed that the output is not equal to the example we reviewed in the first section. Note that, to clarify, in the comments we show the corresponding values to each stem. For example, if you want to make a stem-and-leaf plot for the data set of 100, 105, 110, 120, 124, 126, 130, 131, and 132, you can use the highest place value to create the stem. The output is the text displayed in the following block. You can create a simple stem plot typing: stem(data) It should be noted that if the input argument contains non-finite or missing values they are not taken into account. Call the nexttile function to create the axes objects ax1 and ax2. Call the tiledlayout function to create a 2-by-1 tiled chart layout. The syntax of the function is as follows: stem(x, # Numeric vector Starting in R2019b, you can display a tiling of plots using the tiledlayout and nexttile functions. The stem function allows you to create a stem and leaf plot in R.
