Histogram Struggle

[emma_mcl]

Hi! I'm new at this so I don't know if I've written this in the right place!
I'm trying to make a histogram of two means to compare them. I am comparing sex (Male and Female) and their average of a total. I would like to compare the two sexes average results, however I'm not sure how to do it. So far I have done

mean(SexF$Price Total)
mean(SexM$Price Total) #to collect the mean values

I then don't know how to insert these into a histogram, I tried to rename them using the following code (used the same code for Female, F) but when I put them into a histogram it says " 'x' must be numeric."
PriceTotalM<-mean(SexM$Price Total)

I also tried to build a histogram the code below, however nothing came from it.
hist(Result$PriceTotalM, PriceTotalF)

I'm wondering if anyone has advice on what I've done wrong or how to solve this?
Thanks

You have definitely written this in (one of) the right place.

We probably should have a bit more information on exactly what you are doing. It is often easy to do something in many different ways in R.

Here are some suggestions:

FAQ: How to do a minimal reproducible example ( reprex ) for beginners

A minimal reproducible example consists of the following items: A minimal dataset, necessary to reproduce the issue The minimal runnable code necessary to reproduce the issue, which can be run on the given dataset, and including the necessary information on the used packages. Let's quickly go over each one of these with examples: Minimal Dataset (Sample Data) You need to provide a data frame that is small enough to be (reasonably) pasted on a post, but big enough to reproduce your issue. Let's say, as an example, that you are working with the iris data frame head(iris) #> Sepal.Length Sepal.Width Petal.Length Petal.Width Species #> 1 5.1 3.5 1.4 0.…
