tikzDevice in Lyx

Question

Would like to use the tikzDevice in conjunction with knitr, but am unable to get Yihui's Code Externalization (Stat546-HW4-Xie.lyx) demo working.

Rscript is in the path and Lyx 'view messages' reveals:

13:07:08.450: Quitting from lines 68-68 (C:/Users/awhite/AppData/Local/Temp/lyx_tmpdir.Hp6728/lyx_tmpbuf2/Stat546-HW4-Xie.Rnw)

Error: Cannot convert file

I've followed the setup as per "Using Sweave with Lyx" and ensured that the R code works from within RStudio.

Thanks in advance for your help.

Lyx version: 2.0.7 R: 3.0.2 MiKTeX : 2.9

UPDATE:

What I've just discovered is that when I copy the files (.lyx, .R, .csv) out of dropbox and run from desktop it works. Spaces in the dropbox path a problem?

Answer 1

I had similar problem with Google Drive.

Try shutting the Dropbox application down when you compile your file or at least disable its synchronization.

I tried it and it worked with Google Drive. Spaces in path to the file didn't affect the result.
