geom_point requires the following missing aesthetics:

geom_point requires the following missing aesthetics:, We’ll show you how to debug the ggplot2 “Error: geom point requires the following missing aesthetics: y” in R programming in this article.

Packages with Sample Data and Add-Ons

Consider the following examples.

df <- data.frame(col1 = 1:10,col2 = 20:11)
df

col1 col2
1     1   20
2     2   19
3     3   18
4     4   17
5     5   16
6     6   15
7     7   14
8     8   13
9     9   12
10   10   11

The result of the RStudio console is seen above, which reveals that our example data comprises ten rows and two columns.

If we wish to use the ggplot2 package to plot our data, we must also install and load ggplot2.

#install.packages("ggplot2")     
library("ggplot2")

Example 1: Reproduce the Error: geom_point requires the following missing aesthetics:

This example explains how to use the R programming language to mimic the ggplot2 “Error: geom point requires the following missing aesthetics: y” error.

Let’s say we want to make a scatterplot with ggplot2. Then we may try running the following R code:

ggplot(df, aes(x = col1)) +   geom_point()

Error in `check_required_aesthetics()`:
! geom_point requires the following missing aesthetics: y

The RStudio output has reported “Error: geom point requires the following missing aesthetics: y,” as you can see.

This occurred because just one variable was supplied in the aes function of the ggplot2 package.

So, what are our options for resolving this issue?

Example 2: Correct the Error: geom point is missing the following aesthetics.

Data Normalization in R » finnstats

This example demonstrates how to remove the error “Error: geom point requires the following missing aesthetics: y.”

Within the aes function, we must supply a second column for this task:

ggplot(data, aes(x = col1, y = col2)) +
geom_point()

The ggplot2 dotplot shown in Figure 1 was plotted after running the prior R programming code.
