A Question About Histograms

[TJ37043]

How do you add a title to a histogram of a dataset? Any assistance is greatly appreciated in this matter.

Here is my code:
hist(county, main="Skewness of Dataset: County")

Here is the output (notice there is not title in the output):

Sample dataset:

[technocrat]

See the FAQ: How to do a minimal reproducible example reprex for beginners.

hist(mtcars$mpg, 
main = "Distribution of mileage in the mtcars dataset",
     xlab = "Miles per gallon")

This suggests that the problem arises from however the output of multiple histograms is being generated.

[TJ37043]

I did not put my dataset up because there are 6000 data points, and the last time I put a sample, someone complained. How much of the dataset should I put up as a reprex?

[technocrat]

It doesn't have to be all your data, your data at all if there is another data set available in an R package or otherwise, or even real data. Just to illustrate how you get to the image.

[TJ37043]

I posted some of the data.

[technocrat]

As a reprex, the data should look like this, produced with

dput(county)

or preferably

county <- data.frame(

So, the next question is how are you producing the output shown from the county data frame with the command hist(county, main = "something")

[TJ37043]

I input the r code I shared above and it produced the graph shown. The only thing missing from it was the title.

[TJ37043]

I figured it out.

hist(county)
mtext("Skewness of Dataset: County", side=3, line=3)
