            you are pretty close and only needed a few modifications. the major change is adding in an lapply() to loop through the vars input to create a list of tbl_summary objects. Then I create the tab spanner names from the inputs of vars and append the t0 table to the list created by the lapply(). then you can pass tlist2 to tbl_merge() with the names created with tabspannername to dynamically label the tables.

            How to transfer my files to R Projects, and then to GitHub?
            Asked 2022-Mar-20 at 07:25

            I have 3 r scripts;

            1. data1.r
            2. data2.r
            3. graph1.r

            the two data files, run some math and generate 2 separate data files, which I save in my working directory. I then call these two files in graph1.r and use it to plot the data.

            How can I organise and create an R project which has;

            • these two data files - data1.r and data2.r
            • another file which calls these files (graph1.r)
            • Output of graph1.r

            I would then like to share all of this on GitHub (I know how to do this part).

            I have broken my answer into three parts:

            • The question in your title
            • The reworded question in your text
            • What I, based on your comments, believe you are actually asking
            How to transfer my files to R Projects, and then to GitHub?

            From RStudio, just create a new project and move your files to this folder. You can then initialize this folder with git using git init.

            How would [my included code] need to be executed inside a project?

            You don't need to change anything in your example code. If you just place your files in a project folder they will run just fine.

            An R project mainly takes care of the following for you:

            • Working directory (it's always set to the project folder)
            • File paths (all paths are relative to the project root folder)
            • Settings (you can set project specific settings)

            Further, many external packages are meant to work with projects, making many task easier for you. A project is also a very good starting point for sharing your code with Git.

            What would be a good workflow for working with multiple scripts in an R project?

            One common way of organizing multiple scripts is to make a new script calling the other scripts in order. Typically, I number the scripts so it's easy to see the order to call them. For example, here I would create 00_main.R and include the code:

            Replace pattern at end of a string by pattern at the beginning
            Asked 2021-Sep-17 at 08:34

            I'm very new to regular expressions, so my apologies if this is an obviously stupid question.

            Suppose I have a string of the form (c"fair*", "beaut*") and I want to replace the asterisk (*) at the end by a caret (^) at the beginning: c("^fair", "^beaut"). How could I go about doing that using stringr? I have read this excellent introduction to regexp, but did not figure it out. I made several attempts with stringr::str_replace_all(), to no avail. The issue seems to be that the replacement in stringr::str_replace_all() can't be a regexp. Is that so? If yes, is there any other way to do this?

            It looks like I "solved" the problem by changing an option in the _common.R file from crayon.enabled=TRUE to crayon.enabled=FALSE. This removed the ANSI escape sequences from the book. Previously I had tried setting options(crayon.enabled=FALSE) in my R session, but this was evidently being overridden by the setting in _common.R.
