How to create a box plot in R?
In R, boxplot (and whisker plot) is created using the boxplot() function. The boxplot() function takes in any number of numeric vectors, drawing a boxplot for each vector. You can also pass in a list (or data frame) with numeric vectors as its components.
How to create a boxplot in ggplot2?
For further details read the complete ggplot2 boxplots tutorial. The input of the ggplot library has to be a data frame, so you will need convert the vector to data.frame class. Then, you can use the geom_boxplot function to create and customize the box and the stat_boxplot function to add the error bars.
How to plot box plots for multiple groups?
In case of plotting boxplots for multiple groups in the same graph, you can also specify a formula as input. In addition, you can customize the resulting box plot with several arguments.
How to make your boxplots thinner in R?
We can align our boxplots horizontally with the argument horizontal = TRUE: Figure 4: Horizontally Aligned Boxplots. As you can see based on Figure 4, the previous R syntax changed the X- and Y-Axes of our plot. If we want to make the middle of our boxplots thinner, we can use the notch argument:
How to adjust the boxplot in ggplot2?
The stat_boxplot function is the same, but our custom function to calculate counts need to be adjusted so the position would be in log units. This is used instead of scale_y_continuous. Adds nice log ticks to the right (“r”) and left (“l”) side. This function forces the y-axis breaks to be on every 10^x.
Which is the formula for the boxplot function?
Boxplot form Formula The function boxplot () can also take in formulas of the form y~x where, y is a numeric vector which is grouped according to the value of x. For example, in our dataset airquality, the Temp can be our numeric vector. Month can be our grouping variable, so that we get the boxplot for each month separately.

How to make multiple your plots in ggplot2?
You may have already heard of ways to put multiple R plots into a single figure – specifying mfrow or mfcol arguments to par, split.screen, and layout are all ways to do this. However, there are other methods to do this that are optimized for ggplot2 plots.
Is there a function to draw a boxplot?
The boxplot () function takes in any number of numeric vectors, drawing a boxplot for each vector. You can also pass in a list (or data frame) with numeric vectors as its components.
