How to Modify Colors of Axis Labels & Values in Base R Graph (Example Code)

In this R programming post you’ll learn how to adjust axis colors in a plot.

Creating Example Data

data(iris)                     # Loading example data frame
head(iris)
#   Sepal.Length Sepal.Width Petal.Length Petal.Width Species
# 1          5.1         3.5          1.4         0.2  setosa
# 2          4.9         3.0          1.4         0.2  setosa
# 3          4.7         3.2          1.3         0.2  setosa
# 4          4.6         3.1          1.5         0.2  setosa
# 5          5.0         3.6          1.4         0.2  setosa
# 6          5.4         3.9          1.7         0.4  setosa
plot(iris$Sepal.Length,        # Draw graph in black
     iris$Sepal.Width)

Example: Modify Colors of Axis Labels & Values Using col.lab & col.axis Arguments

plot(iris$Sepal.Length,        # Draw graph with manual axis colors
     iris$Sepal.Width,
     col.lab = "green",        # Change color of axis labels
     col.axis = "cyan")        # Change color of axis values
