Box width too narrow and Reference Classes not supported?

[jankowtf]

Hi Yihui,

kudos for knitr, this thing ROCKS!!

I just played around a bit with it and it looks great!
Came across two issues though:

1. The boxes that contain R code are just a tiny bit too narrow on the right hand side (just try making (x <- rnorm(20)) a bit larger in your minimal example and you'll see)
2. Code for reference classes does not seem to work (setRefClass etcl).

It'd be great if you could take a look at this once you get a chance!

Thanks a lot,
Janko

PS: I'm on Windows XP SP2, R 2.14.0, LyX 2.0.2, MikTeX 2.9.

1. sorry I do not quite understand what you mean; which boxes are you talking about? or could you show me a screenshot? (e.g. via imgur.com)
2. I tried the examples in ?setRefClass and they worked, so what exactly is your problem?

Thanks!

1. Sorry if I might not have used the correct LaTeX terminology, but I
   meant the gray box that is put around R code.
2. Hm, that's strange. Do you know why it might not work for me? I'm
   running all my R related stuff from a USB drive, but set things like
   'lib' and 'destdir', windows PATH stuff etc. accordingly. I'm using LyX
   2.0.2 and MikTeX 2.9, both portable as well.

1. Do you get similar output as I did? https://github.com/downloads/yihui/knitr/knitr-minimal.pdf If yes, could you point out how wide the gray shading should be?
2. You need to be more specific on "not working" -- what is not working for setRefClass? highlighting? or R code won't run? or something else?

I'm sorry Yihui, seems like you didn't receive the attachment in my last email (an own example based on your minimal example which shows exactly what you asked for) and without it my last message was indeed not really informative ;-)

Or does this email address does not support attachments? I'm trying againd, if it doesn't work let me know and I'll put it up on the web somewhere.

Best regards,

janko

Ahh!! It is finally clear to me what you mean now... First off, GitHub emails do not support attachment, so I did not receive anything in your previous messages (that is the source of confusion).

1. The problem is that your output is too wide (exceeding the margin), rather than the box is too narrow. The fix is to set options(width = a.smaller.number) (e.g. options(width = 60)).
2. new() is in the methods package, and at the moment you seem to need to load it explicitly; I do not know what happened to your R session, but the methods package should be loaded automatically... I will double check.

[yihui]

Now I have found the answer for your second question: when we run an R script via Rscript, the methods package is not loaded by default; see ?Rscript for details. You have to load it explicitly by library(methods) in your code.

Great, thanks!
