Basically there's small simulation going on, so if you don't need any
simulation just a small plot it will go in less then a second. Haven't seen
any other solution :-)
Oh, my ... it's worse than I thought. Not only does it run things so you have
to wait forever - it actually installs packages behind your back! Wow, now
there is the nightmare abuse of \Sexpr - the malicious package retrieves
private data from your machine and deletes your files... and I was worrying
about leaving a tiny crack open for Rhttpd injection attacks - yet there is a
big gaping door open to all packages ... Does it mean we need more stringent
checks on Rd files now as well since they contain code?
I don't think it's any more of a security problem than packages have
always had, since they can execute arbitrary code when you load them.
What is interesting, though, is that the code gets executed even if html is not
the back-end (e.g., in terminal) .. is this a bug?
The docs say that \Sexpr is evaluated before \if, so probably not...

it only takes long because there's a simulation going on in the background...

Hi,
There's a possibility to put images into documentation files. Have a look at
the package visualizationTools to see how it works. The original idea is/was
by Romain Francois as far as i remember.
For instance have a look at the documentation for the function CLT
Interesting - ?CLT takes forever (about 30s) on a fairly fast machine (8-core
Xeon) - every time! That sort of defeats the purpose of help pages ... so
whatever it's doing (behind your back - the help in the console still shows no
images, obviously), I would not recommend it as it makes the help unusable.
Cheers,

I’m trying to figure out how to put images into my package’s help
documentation. I’ve gotten to the point where I can put the images in the
/inst/doc/ directory. I have also gotten to the point where I have
package
checks without any warnings. I couldn’t find the terms “picture,”
“image,”
or “graphic” in a text search within the Writing R Extensions: 2 Writing
R
documentation files
I think you're asking the wrong question. You should be asking: "Can
I include images in help files?". As far as I know, the answer is no.
You might be able to do it for specific output formats. See
