One error you may encounter when using R is:
Error in plot.window(...) : need finite 'xlim' values
This error occurs when you attempt to create a plot in R and use either a character vector or a vector with only NA values on the x-axis.
The following examples show two different scenarios where this error may occur in practice.
Example 1: Error with Character Vector
Suppose attempt to create a scatterplot using the following code:
#define data
x #attempt to create scatterplot
plot(x, y)
Error in plot.window(...) : need finite 'xlim' values
We receive an error because the vector that we used for the x-axis values is a character vector.
To fix this error, we simply need to supply a numeric vector to the x-axis:
#define two numeric vectors
x #create scatterplot
plot(x, y)
We’re able to create the scatterplot without any errors because we supplied a numeric vector for the x-axis.
Example 2: Error with Vector of NA Values
Suppose attempt to create a scatterplot using the following code:
#define data
x #attempt to create scatterplot
plot(x, y)
Error in plot.window(...) : need finite 'xlim' values
We receive an error because the vector that we used for the x-axis values is a vector with only NA values.
To fix this error, we simply need to supply a numeric vector to the x-axis:
#define two numeric vectors
x #create scatterplot
plot(x, y)
Once again we’re able to successfully create a scatterplot with no errors because we used a numeric vector for the x-axis.
