Using the iris dataset in R, I write a function to plot a confusion matrix.

Good afternoon ,

Assume we have the following :

I would like to add column and row % to the following figure. For instance, across the top of the plot (outside) it would be 1%, 6%, 17%, and 76%, representing the distribution for Coder 1. Down the right (outside) would be the row distributions.

Maybe this is better as a table, but it feels like it wants to be a figure.

I am trying to draw the following: Given a bar chart in ggplot similar to this one: a grouped bar chart, flipped over x axis.

I would like to draw a line on top of each of the bars. The longitude of the line is defined in the dataframe df2. (think about it as some sort of standard deviation)

The longitude of the line is defined, and it will be centered at the highest point of each bar. As you can see this is not similar to a boxplot, it is a line that will always remain constant and centered on top of each bar.

So I was wondering if it was possible to do this with the code I am showing in the next Section. In excel it is quite fast to do this using what is called a Box and wisker plot. The final result should look like the following:

This is the code I am currently using, hope someone can please help me out.

I want to iteratively process a master list of comparisons using group_walk() or group_map() as an alternative method to import batches of .csv files.

I would like to input a dataset that looks like this:

I want to use the function epi_analysis and export a csv for each Test Assay (in this example Assay1, Assay2, and Assay3). So far I have:

I'm trying to parse this .txt file in R: https://ftp.expasy.org/databases/cellosaurus/cellosaurus.txt

It's essentially a single column data frame of some ~2 million rows, with each entity being described by multiple rows and bookended by rows containing the string "//".

Ideally, I could capture each entity, made up of multiple rows, as a list element by splitting at "//", but I'm not sure of the most efficient way to go about this.

Any help is much appreciated.

EDIT:

Here's a snippet of what I'm working with:

I was wondering if it is possible to do the following in R:

I am doing a dodged barchart and using the geom error bar. I am currently using the following example:

I have two directories containing folders and files, as seen below

I am trying to extract the beta values from a model determined using train() from the caret package.
