Hello Scott, I tried your suggestion and installed knitr using RGui, but to no avail - LyX 2.4.3 still cannot find knitr. Thank you for your direct reply to me, as I don't see my question posted on lyx-users. Is there a delay before questions are posted? It would be of interest to see if my problem is an isolated one, or if others have experienced it and resolved it in some way.
Sincerely, Tom ________________________________ From: Scott Kostyshak Sent: Friday, January 17, 2025 2:21 AM To: Thomas Philips Cc: [email protected]; Tianqi Wang; 'Stoyan Stoyanov' Subject: Re: Trouble with knitr in LyX 2.4.3 On Thu, Jan 16, 2025 at 10:27:47PM +0000, Thomas Philips wrote: > Dear all, > I have just installed LyX 2.4.3 alongside LyX 2.3.8 on my Windows 11 PC with > R 4.4.2.

The reason behind this suggestion: I wonder if RStudio is installing and loading packages into a directory that vanilla R doesn't know about. To install on vanilla R, open R (not RStudio) and enter the following: install.packages("knitr") Best, Scott
