Nocturnal | A simple macOS app to toggle dark mode with one click | Menu library

I am trying to remove characters of comments(/* */) from the String s, but I am not sure how I extract them, especially, from the second comment. This is my code:

Here is the code

I am working with a nocturnal species and am trying to label GPS fixes recorded overnights by date and time periods. The GPS fixes were recorded between 19:00:00 one night and 05:00:00 the following morning for ~ 80 days. Each night period span two days (obviously). I want to organises the fixes by night as opposed to date so the animal movement isn't split in the middle of the active period. I am having issues getting this to work correctly. I would like to create a new column with an ID for a collection of days in a period (e.g. 1-week) but would also like to create a column for each separate night.

When I first read in the data it looks like the following (noting this is not my data but an example of 4 columns that exist within the dataset and its structure):

I have a dataframe consisting of three columns: x, ID and date_time. The “x” column is a recording of a variable x that occurs every five minutes, ID indicate what is being recorded, while date_time indicates when. See a piece of the dataframe below.

From this dataframe I would like to calculate a new dataframe that has seven columns: "Measurement", "ID" and "Date", “x_4_5_night_15min_yes/no”, “x_4_5_night_time_15min”, “x_4_5_night_events_15min”, “x_<4_night_15min”

1. “Measurement”. This column should tell what number measurement this was of a given ID. A measurement starts at 23:00:00 and then runs until 22:59:59 the next day. A measurement however starts at random times and the duration of the first measurement is thus not 24 hours. Neither is the last measurement 24 hours.
2. “ID”. Indicate the ID of a given measurement.
3. Date”. This column should show the date of the last recording in a given measurement in this format: yyyy.mm.dd.
4. “x_4_5_night_events_15min”. ”. A measurement is divided into a day (7:00:00-22:59:59) and a night (23:00:00-6:59:59). This column should give the number of nocturnal episodes with x between 4 and 5 (both included). However, only periods lasting at least 15 minutes should be counted. E.g. two consecutive recordings between 4 and 5 that are preceded and followed by a recording above 5 should not be included, as x would only have been between 4 and 5 for 10 minutes.
5. “x_4_5_night_15min_yes/no. This column should indicate with a yes (1) or no (0) if x was between 4 and 5 (both included) a given night for a least 15 minutes. Same criteria for understanding 15 minutes apply as described in 4.
6. “x_4_5_night_time_15min”. This column should give the amount of time x was between 4 and 5 (both included) a given night. However, only periods lasting at least 15 minutes should be included. Same criteria for understanding 15 minutes apply as described in 4.
7. “x_<4_night_events _15min”. This column should indicate with a yes (1) or no (0) if x was below 4 a given night for at least 15 minutes. Same criteria for understanding 15 minutes apply as described in 4.

There should be a row for every unique measurement. So far I have a code that returns the columns: "Measurement", "ID" and "Date” correctly:

I have two tables in database, entries that only have column words, and another table worddictionary with columns word, definition and auduiourl,

So, I am attempting to create a ggbiplot of a PCA of prey order in the diet of diurnal and nocturnal raptors, but the problem is that the ggbiplot function automatically creates arrows for each order. There are only about 8 orders that are significant for my research (i.e., have a value in PC1 and PC2 that is greater than or equal to 0.1).

This is what the ggbiplot looks like right now:

I've also been able to successfully remove all of the arrows using the var.axes = FALSE function to get this plot:

But the problem is that from either plot, I'm not sure how to either remove only a portion of the arrows so that I can just keep the 8 that I need, or add those 8 back to the plot from scratch after I remove all of the arrows.

Edit: I want the PC values for all 38 orders to still be factored into the plot, I just want to remove the unnecessary arrows until there are just 8 left.

Reproducible Example:

I am using R to analyse some ecological data, and when I try to create a boxplot two different boxes appear for one of my variables.

Here is my code:

I am needing to write a function that takes in a parameter. If the parameter divided by 2 is NaN it is to return "FLYING NOCTURNAL MAMMAL MAN!" Otherwise it is to return the result of the parameter divided by 2. I feel like what I am trying is pretty close. Any help would be greatly appreciated! Thanks.

Here is what I am trying:

I have two divs, side by side, where one (right) has more content that the other (left). I've been trying to have the right one, vertical align so it's centered in the middle of the left one.
