When trying to plot a histogram for a class project, I keep getting an error message saying 'x must be numeric.' I am trying to plot a histogram of Democratic vote share (which I created a variable for as dem_pct) in open-seat races (df$inc_D==0 & df$inc_R==0) and races with a Democratic incumbent (df$inc_D==1). I checked to see which variables are coming back as non-number, and that is the "state" column, which I expected. I have been trying to create a new variable "Dem_Inc" to represent the vote share during years with Dem Incumbents, with OpenSeat meant to represent years without an incumbent.
I have the following code for a histogram I am trying to use:
the histogram snippet you shared relies on my_data$my_variable
after that you wrote a lot of code, none of which even mentions my_data$my_variable.
I think there are some issues with your code. there are a lot of statements that calculate, but then don't store their results in any other variable to be referenceable again later. i.e. the various mean() calculations you perform. They dont seem to go anywhere...
my_data$my_variable is just a template given to me. My data would be df, and I believe my variable would be some combination of dem_pct and the two variables I created (inc_D==0 & inc_R==0 and then inc_D==1). Here is the code I have with a lot of the junk taken out.
I read the instructions on how to produce the reprex and I am honestly super confused. This is my 2nd week using R, so I've had a hard time with this assignment to say the least. Tried to go a different avenues my professor recommended and I still feel lost.

I was able to get this out of the reprex. I don't think its overly hopeful, but its my shot at it.
I think the most important thing to learn when you are starting with R is how to properly and effectively ask for help, so even if you are confused you should at least try to make a reproducible example. If we had access to sample data on a proper format we could pretty easily give you a working solution for your problem.
