How to plot means for two treatment types per Temperature

[AmberH]

Hi, I'm quite new to R and am using it for my marine biology degree.
I am trying to produce a graph plotting y='Mean Beats' and x=Temperature but I have two different categories to plot as individual lines -'Fed' and 'Starved' which are under the column 'Treatment'. I want to plot the means of each category per temperature but don't know the right code for it. I'll attach what I've got so far, my code, a portion of my table for reference as well as a screenshot of what I'm aiming to create.. Hope someone has some advice :)!!

Hi!

I'm afraid screenshots of your data and code are not very helpful and even a bad practice here.

To help us help you, could you please prepare a reproducible example (reprex) illustrating your issue? Please have a look at this guide, to see how to create one:

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.…
