I'm trying to plot shannon diversity for BTO data, however, to use the vegan package, I must place the data into matrix form. This is not a problem, however, I have various variables to group shannon diversity by however, I'm having difficulties subsetting this into code.

I need a way to calculate diversity by localicity_id + Postcode + week + year, using this code:

I am really struggling to understant POSIXct within ggplot. I would like to compute an histogram of my data which tells me in which hours during the night I have more records within my dataset.

I understand if I have to convert something using as.POSIXct I need a column in my original dataset with date + time or at least date. The point is I only have time (HH:MM:SS), and I am not interested at all in the date itself. When applying:

I would like to know how I can save the sate of my checkbox? The checkbox is in a listview of birds. If you click the box it means you have seen that bird and saves the state. I have tried doing it with preferences but don't know if I am on the right track.

UPDATE

Here is the xaml for the BirdListZA

I would like to compute a graph that tells me the increasing nº of species I am recording thorugh time, preferably with ggplot and geom_line. So it would be something like: the first day I had one species, day 1 equals 1 species. 2nd day I detected 2 new species, day 2 should equal 3 species. If on day 5 I detected another new species, day five should equal 4 species, and so on.

It's probably an easy thing but couldn't find the way to an example within the forum, probably because I am not using the right words. What I would like from my data would be something like (don't take numbers as reference, my total number of species is only 15, no 52 like in this plot!):

You can use this subset of my dataset as a reproducible example:

I'm scraping an html file with a table like this:

i try to get a random combination of different sentences. So i have five different types of sentences. Each type has between 5-8 example sentences. What i try to achieve ist that i always get one random sentence of each type. I've already tried a few things, but i don't get it really randomly. With the code i have there are only a few combinations that where shown again and again. Sometimes there appears "undefined" instead of certain sentences. Can someone help me, to get the it running really randomly and without the "undefined" thing.

Thanks a lot!

here's what i have already:

I am trying to get all the date values in a json array for the dates inside the england-and-wales value.The array that like this (except it has a lot more values) the json array is here : https://www.gov.uk/bank-holidays.json

I am using as a Latex renderer in my flutter project. I want to add a latex value to an existing Catex object. I have a List of Strings which hold latex values and a listview to display them in order. I want to add a list item to the Catex every time an OnTap method is called. so far, + operator is not supported

The operator '+' isn't defined for the type 'CaTeX'.
