There may be more elegant solutions, but you could try something like finding the number of unique values in whatever color is specified. For instance:

By manually adjusting the position of the image with xmin/xmax & ymin/ymax, fixing the pitch of rows and columns with coord_fixed(clip = "off) and expanding the plot.margin in theme I was able to get something that seems like it will work.

As the error message says, you need to always pass a path to the functions.firestore.document(...) function, to determine on which document paths the function triggers.

You do this correctly here:

Maybe this is what you are looking for:

1. Convert your taxa variables to factor with the levels equal to your taxas variable, i.e. to include all levels from both datasets.

2. Add argument drop=FALSE to both scale_fill_manual to prevent dropping of unused factor levels.

Note: I only added the relevant parts of the code and set the seed to 42 at the beginning of the script.

It really take a lot of time to reproduce your case as you have so many packages that I didn't use :)

Explaination of the issue: ggplot does not render any graph at the time you call the geom and passing data and mapping aes. ggplot just store the name reference to the data variable. Only when render it actually get the value and plot. In your case, you are passing reference dd[[col]] and as col change value through for loop while ggplot always reference to col so it ended render two bar of the same data of the last column value is Column2. You can verify this by changing order of the column and put Column1 at last then you will see two bar of Column1 instead.

Solution: create unique reference for each loop

Try the following:

1. There's a difference between a STUN and a TURN server, Google provides free STUN servers to use, while it's not recommended for an app because you want to have control when things go wrong, it's definitely fine for a small project that's for learning if that's your case and can reduce your project complexity. (I also don't think it's that bad to use it on small projects that have some users)

2. If that's not the case, you are going to need to set these up yourself. There's plenty of tutorials online on how to do it, but you do need a server. The gist of it is opening certain ports and installing it using some basic tools like coturn. I'd recommend you follow a guide like that from start to finish, like this one:

1. Once it's setup, you need to use this in your app, like this:

Your problem is because you are returning a number from the function and casting it to a Boolean so every number will truncated to a True value.

You should check inside the function whether it’s a palindrome or not and return a 1/0 result or even better a Boolean value.

The viridis package is one option, e.g. viridis::viridis(30) will do it.
