Commendations, Steve, for the excellent & concise refresher on R's powerful '$'!
As one who has been programming with R for well over a decade, I found your article to be a great refresher regarding what has become 'muscle memory' (as in: I write the code using well-used syntax patterns; not necessarily with full recollection as to why I apply a specific pattern).
Looking forward to reading more of your useful posts!
With thanks, Plane Wryter

Thank you for reading! I'm glad you found the article useful and refreshing. I do try to write consistently Monday through Friday, with Monday, Tuesday and Thursday being R
Wednesday being C (I got turned around this week) and
Friday being Linux.

I am chronicling my journey learning C and Linux so mistakes may occur and feedback is always appreciated.

Have a great day!
