Dear list,
I would like to make a Sweave document that, for a given package,
automatically inserts the graphical outputs obtained when runing
the example code of high level plot functions. That is, for the
"graphics" base package, something like this:
http://pbil.univ-lyon1.fr/R/fichestd/tdr79.pdf
For this, I need the list of high level plot functions of a
given package. I have encountered a problem when calling twice the
help.search() function which is illustrated bellow:
[rufus:~] lobry% R --vanilla --quiet
> sessionInfo()
Version 2.3.0 (2006-04-24)
powerpc-apple-darwin8.6.0
attached base packages:
[1] "methods" "stats" "graphics" "grDevices" "utils" "datasets"
[7] "base"
> help.search(package = "graphics", keyword = "hplot")
#this one is OK, but not the next one:
> help.search(package = "stats", keyword = "hplot")
Erreur dans help.search(package = "stats", keyword = "hplot") :
could not find package 'stats'
> q()
#Now, if I switch the call order:
[rufus:~] lobry% R --vanilla --quiet
> help.search(package = "stats", keyword = "hplot")
#this one is OK, but not the next one:
> help.search(package = "graphics", keyword = "hplot")
Erreur dans help.search(package = "graphics", keyword = "hplot") :
could not find package 'graphics'
> q()
[rufus:~] lobry%
Is there something obvious I'm missing?
Thanks for any hint,
Jean.
