Any chance one of you has a tip for this shiny-bslib-related issue? Seems like a simple one (just the navbar background color!) but I haven't come up with a solution, #rstats: community.rstudio.com/t/boot…

Bootstrap navbar variables not working in bslib 0.6.1 but working in 0.5

Hi, this must be something simple, but I'm finding that the bootstrap 5 navbar variables are not working for me using bslib version 0.6.1. Note that the bootstrap variable body-bg works in both...

I didn't realize that the stringr R package had added a fixed() modifier like gsub's fixed = TRUE so that literal text is compared, #rstats. Example: library(stringr) str_replace("my (dog) has fleas", "(dog)", "dog") str_replace("my (dog) has fleas", fixed("(dog)"), "dog")

A handy git command -- this will give you the git commit where a line of text got removed: git log -S 'text that accidentally got removed' /path/to/file

If you need to generate a CREATE TABLE statement for a table in #rstats the DBI::sqlCreateTable() function is a good place to start.

Boring but handy. Browse to a directory on your computer from #rstats with this command. I'm finding it useful when I create a temporary directory and want to review what's in there. tempdir_path <- tempdir() utils::browseURL(tempdir_path)

Super-succinct post on how easy it is to query a remote file (without downloading the whole thing!) using parquet and DuckDB with #rstats r.iresmi.net/posts/2023/fast…

Fast remote parquet – r.iresmi.net
