How do I label a Boxplot in R?

The common way to put labels on the axes of a plot is by using the arguments xlab and ylab. As you can see from the image above, the label on the Y axis is place very well and we can keep it. On the other hand, the label on the X axis is drawn right below the stations names and it does not look good.

How many labels does a box plot have?

A box and whisker plot—also called a box plot—displays the five-number summary of a set of data. The five-number summary is the minimum, first quartile, median, third quartile, and maximum. In a box plot, we draw a box from the first quartile to the third quartile. A vertical line goes through the box at the median.

How do you label a Boxplot?

To construct a box plot, use a horizontal or vertical number line and a rectangular box. The smallest and largest data values label the endpoints of the axis. The first quartile marks one end of the box and the third quartile marks the other end of the box.

How do you make multiple box plots in R?

Plot multiple boxplots in one graph in R

  1. x: This parameter sets as a vector or a formula.
  2. data: This parameter sets the data frame.
  3. notch: This parameter is the label for horizontal axis.
  4. varwidth: This parameter is a logical value.
  5. main: This parameter is the title of the chart.

How do I add color to a boxplot in R?

We can add fill color to boxplots using fill argument inside aesthetics function aes() by assigning the variable to it. In this example, we fill boxplots with colors using the variable “age_group” by specifying fill=age_group. ggplot2 automatically uses a default color theme to fill the boxplots with colors.

How do you do a boxplot in R?

Boxplots are created in R by using the boxplot() function….Syntax

  1. x is a vector or a formula.
  2. data is the data frame.
  3. notch is a logical value. Set as TRUE to draw a notch.
  4. varwidth is a logical value.
  5. names are the group labels which will be printed under each boxplot.
  6. main is used to give a title to the graph.

How do you compare two box plots?

Guidelines for comparing boxplots

  1. Compare the respective medians, to compare location.
  2. Compare the interquartile ranges (that is, the box lengths), to compare dispersion.
  3. Look at the overall spread as shown by the adjacent values.
  4. Look for signs of skewness.
  5. Look for potential outliers.

How do I add color to a Boxplot in R?

How do you read box plots?

What is a Boxplot?

  1. The minimum (the smallest number in the data set).
  2. First quartile, Q1, is the far left of the box (or the far right of the left whisker).
  3. The median is shown as a line in the center of the box.
  4. Third quartile, Q3, shown at the far right of the box (at the far left of the right whisker).

How do I add color in R?

In R, colors can be specified either by name (e.g col = “red”) or as a hexadecimal RGB triplet (such as col = “#FFCC00”). You can also use other color systems such as ones taken from the RColorBrewer package.
