how to write an Augmented Matrix
Dear Lyx Users, Could you please suggest me writing an Augmented matrix in LyX? In this matrix, I actually need to type a bar between second and third column of a matrix. I have pasted below the Augmented matrix too for your information. Thanks, Regards, Shyam Kumar Basnet Uppsala, Sweden http://www.mathwords.com/a/a_assets/a128.gif <>

Removing the noweb module fixed the error and fixing the path fixed the compile error. I don't get this error on Ubuntu so I assume I must have a more complete installation on Ubuntu. Thanks again Liviu and Julien, a great relief to get this sorted. Graham

I knew I needed Sweave, just not sure about noweb. The file has never seen 1.6, it was produced in Lyx 2 on Ubuntu 11.04, but then opened in the Mac after I had upgraded to the existing 1.6 to 2.0. I did say this in original post, and in the post when I uploaded the file :-) Graham

As you will now have seen, none of these things were in fact missing. The error was caused by the path in the Lyx doc pointing to the text file used by R, which was pointing somewhere that Lyx on the Mac didn't understand. Changing the path has fixed everything so inspite of the error message the missing elements were not in fact missing. I did read the section in the help file and the follow up in the customisation guide. I think you have identified my key area of confusion, for as you can see in subsequent posts, based on those instructions I was looking for a Latex package called "literate" to install, which I couldn't find.

I'm afraid I don't understand what you are asking me to try. As the doc has already worked with SWeave, the modules SWeave and Noweb are loaded automatically, which is why I assume I am getting the error as soon as I open the document the lyx. And again the article class is chosen as that is what class of the document I am loading. So I don't reall know what it is you want me to try, sorry. Also when you ask for a small Lyx Sweave file, I haven't reached the stage of trying to compile the document because of the error messages. However, I have just tried to complile it and get an error. "An error occurred while running: Rscript --verbose --no-save --no-restore "/Applications/LyX.app/Contents/Resources/scripts/lyxsweave.R" "/var/folders/NZ/NZHrfNFJED4D2lK1ptzXHE+++TI/-Tmp-/lyx_tmpdir.L11776/lyx_tmp..."

The message says that a literate->latex converter is missing (although not stated, usually this would be noweave), it also says that the LaTeX package noweb.sty is missing. Is the error message not correct? i.e., do you have "noweave" and "noweb.sty" installed in a useful place in your computer? It might be that LyX is wrong here. When LyX is right, you should follow the instructions in the User's Guide to correct the problem. If you can, please provide feedback on the text in Section 3.1.2.3 (and maybe some suggested replacement text) so that we can change it and make it more understandable. -- Julien

Re: Sweave Snow Leopard and lyx 2.0
Liviu, Many many thanks for this, I knew I would need to edit the file path once I started working with the file, but didn't realise that it could cause an error about installed classes when simply loading the file. No changed "~/Dropbox/projects/R_Anova/Data/Ian.txt" When I was regularly switching between Linux and the Mac, I used this format as it migrated between platforms. But I haven't used the Mac for a long time. Unfortunately, I am having to abandon Linux and switch back to the Mac full time, and I seem to have forgotten everything I knew about the Mac :-( Thanks again, Graham On 21 August 2011 08:24, Liviu Andronic wrote: > On Sun, Aug 21, 2011 at 8:06 AM, Graham Smith wrote: > > I have attached the file that is giving me the problems and just in case > it > > as been missed, this file was produced in Lyx 2.0 in Ubuntu 11.04.
