"unfinished" layout does not produce the figure when the last line of the chunk is a comment

[knokknok]

Not sure how to describe this and what the real cause is but you can try this:

library(knitr)
knit(output='test.tex', text='
<<chunk1>>=
par(mfrow=n2mfrow(9))
for(i in 1:9)
  image(volcano)
# comment
@
<<chunk2>>=
par(mfrow=n2mfrow(9))
for(i in 1:9)
  image(volcano)
@
<<chunk3>>=
par(mfrow=n2mfrow(7))
for(i in 1:7)
  image(volcano)
# comment
@
<<chunk4>>=
par(mfrow=n2mfrow(7))
for(i in 1:7)
  image(volcano)
@
')

On my setup, chunk 3 does not produce a figure.

That is a bug of the evaluate package. I'll try to fix it. Big thanks for making the 600th issue! 😄

Yep I noticed that but I managed to restrain from this kind of behaviour : http://www.xkcd.com/1258/ 😄
