I wrote a short post about the R package development experience with Positron, the new IDE from Posit based on VS Code. I compare the experience with RStudio. This is not a tutorial on R package development in general - there are great resources for that elsewhere.
Awesome - I never new about process substitution. I wanted to convince myself I knew what it was doing, so I started kicking this around a bit. I expected the first command to output "test." I'm not sure I can explain these results:
$ echo <(echo test)
/dev/fd/63
$ cat <(echo test)
test
