Hi everyone,

I am not an R studio pro and I'm struggling quite a bit to create a specific diagram and after looking at every forum not understanding the code I hope someone may help me.

So basically, as the title says, I want to create a stacked barplot with standard deviation error bars.

If my understanding is right, I have to calculate myself the position of the error bars, which is where I'm stuck.

I created already my stack barplot using the very easy following line:

"barplot(as.matrix(dataset))"

I know I can also use ggplot2 but I was also struggling to understand every entry and since my data is already normalised to 100%, the barplot works for me.

But now is my problem, I calculated the standard deviation on Excel all of my data but I don't know how add it into R.

Here is a picture of my own stacked barplot on the right and the other one is a picture of what I would want, on the left.

Thanks a lot if anyone can help me or share some link that I could read
