Problem existed between keyboard and chair (see comments).
knitr + Lyx: missing the knitr->latex converter. (Rscript is in PATH, I swear!) [closed]
Question
It's the standard story -- except that it persists even though I've put the R home directory in LyX's path and even in the Windows PATH environment variable. (I used cmd.exe to verify that Rscript can be called anywhere.)
Lyx 2.0.6, R-3.0.1, knitr 1.2, Windows 7 SP1.
