kandi X-RAY | highr Summary
This is an infrastructure R package for syntax highlighting. It supports LaTeX and HTML output. Not surprisingly, it works best with R code. It attaches markups onto source code, e.g., it turns. This package also has a wrapper function, hi_andre(), for Andre Simon's Highlight package.

QUESTION
The objective of my code is to scrape the information in the Characteristics tab of the following url, preferably as a data frame
...ANSWER
Answered 2021-Jun-11 at 15:38The data is dynamically retrieved from an API call. You can retrieve direct from that url and simplify the json returned to get a dataframe:
QUESTION
I just noticed that read_csv() somehow uses random numbers which is unexpected (at least to me). The corresponding base R function read.csv() does not do that. So, what does read_csv() use the random numbers for? I looked into the documentation but could not find a clear answer to that. Are the random numbers related to the guess_max argument?
ANSWER
Answered 2021-Jun-10 at 19:21tl;dr somewhere deep in the guts of the cli package (called to generate the pretty-printed output about column types), the code is generating a random string to use as a label.
A major clue is that
QUESTION
The example below is a simple one which tries to assert the column y is always positive (y>0). How can I extract the errored data (row 3 with the negative value,into a dataframe maybe, or any convenient object) while allowing the workflow to continue with "cleaned" data?
...ANSWER
Answered 2021-Apr-12 at 09:23This is tricky, and the answer below doesn't solve this 100%. Now there are a number of different ways assertr lets you handle errors/stops, just see ?error_stop (which is the default).
You need to not only filter out rows that fail, but also collect them (all) for later inspection.
Below I wrote my own error handler. It fetches those rows that fail, filter them away, and stores them in the global environment under the varibale my.failed.rows.
QUESTION
When I try to use the new-ish ragg::agg_png() device with ggplot2::ggsave(), the image does not appear to save correctly.
Take the following reprex. I make a simple plot and then save it using the agg_png() function directly, and with ggsave(). The image saved with the agg_png() device directly comes out as expected. However, when I use ggsave(), it's almost like the units are being ignored. You can't tell, but there is a tiny image beneath the final code output. In that output, we can see that the image is only 7x7 px, even though inches have been specified by the units. From this blog post, it doesn't seem like anything extra should be required to make ggsave() work beyond setting device = agg_png.
Are there additional parameters I need to specify? Including session info in case there is something system-specific going on.
...ANSWER
Answered 2021-Mar-02 at 02:33Default units for ragg device is in px. Change it to inches and try this

QUESTION
I have been using WAVEFORMATEX with WaveOut to play audio in Windows, in stereo at rates from 44.1KHz to 192KHz using WAVE_FORMAT_IEEE_FLOAT. The program is written in C++ and compiled in MinGW. This is all working correctly:
Now I'm trying to expand to quadraphonic multi-channel output, which seems to require WAVEFORMATEXTENSIBLE, a superset of WAVEFORMATEX. Here is the relevant code with those changes applied:
ANSWER
Answered 2021-Jan-27 at 12:21If are using a WAVEFORMATEXTENSIBLE structure, you have to indicate that by setting the correct format tag in the "base" WAVEFORMATEX.

QUESTION
Is there a way to calculate the difference between each group efficiently? Ideally, I want to create a new column with mutate() function to show the difference (in one column, in a long format). I don't want to have to do compute the difference between each group individually.
i.e. I want to find the difference in values between each group, on a given date and hour:
arc1045 - arc1046,
arc1045 - arc1047,
arc1045 - arc1048,
arc1045 - arc1050,
arc1046 - arc1047,
arc1046 - arc1048,
.

.
The data frame can be retrieved using the code below.
...ANSWER
Answered 2020-Nov-03 at 14:30You can put your data frame into long form with pivot_longer, then do a full_join to get all combinations by date, hour, and row number. Using distinct you can get unique combinations and remove duplicates (e.g., arc1045 - arc1046 and arc1046 - arc1045).
QUESTION
Given a tibble that lists users, products, and product features, I am attempting to calculate the fraction of distinct product users who have a certain product feature:
ANSWER
Answered 2020-Oct-23 at 18:34The problem is your have multiple values for n_users for each group. The latest version of dplyr allow you to return more than one row per group if your summary function returns multiple values.
If you want to assume all the values for n_users will be the same per group, then you can do
