crayon | css variables linking color names to hex values | Theme library

I am trying to build a function wrapping over haven::read_dta() similar to the wrap_function() defined in the code below.

My wrap_function() has a default variables = NULL, which should be able to pass NULL to haven::read_dta()'s col_select argument if no values are specified. However, passing the NULL from variables to col_select throws an error (i.e. 'Error: Can't find any columns matching col_select in data.').

Can someone help me understand why this happens and how could I build a wrap_function capable of passing a NULL default value to the lower-level function?

Thanks!

I have a camera that is observing a 2d plane below.

I know the size of the world below, and the position of the camera in relation to it.

I wish to rotate the camera by x degrees, but the camera cannot be rotated directly - i can only tell it to look at a point in space.

So i am looking for a function which translates x° of rotation into a y co-ordinate, but i'm struggling to find appropriate search terms.

Specifically, I'm looking for the functional formula - but in case already there's some implementation in my engine that i'm unaware of, i'm implementing with LibGDX.

When I knit any of the CV templates in the R package vitae I get a slightly different error for each one. I've made sure that all the files, including my Rmd file, are in the same directory and I haven't changed the template in any way. When I knit the modern CV template, for example, I get this error message:

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?

I am using the R programming language. I am trying to install the following R library from github: https://rdrr.io/github/ModelOriented/treeshap/

As per the instructions from this website, I copy and pasted the following code to install this library (I could not find this library on CRAN):

When trying to load packages in RStudio or R, I get "image not found" errors, e.g.:

Description

This issue appears to apply to vectorised and loop approaches to renaming several files. Vectorised approach used in reprex below. The bug only seems to present when filenames do not contain meaningful or alphanumeric strings.

Summary

Existing files prior to file.rename:
"1.R" "2.R" "3.R" "4.R" "5.R".
Existing files following file.rename:
"6.R".
Expected output:
"2.R" "3.R" "4.R" "5.R" "6.R"

I am trying to get Github Action to check my package. The packages compiles fine (not even a note) on my computer. I created a yaml script to go into the github workflow directory using usethis::use_github_action_check_standard() but it fails with a bunch of warnings like

No files were found with the provided path: check. No artifacts will be uploaded.

The path check is a temporary directory created by rcmdcheck for storing files. So, I presume it is a problem connected with this command. But everything was created by the usethis utility and nobody else seems to have the same problem.

I looked around a lot and the last fix I tried was to manually add a step to install imported and suggested packages, as suggested in this post, to no avail.

What am I doing wrong? Thanks in advance.

the yaml script is

Consider the following code, where I have two files in my targets pipeline.
