R help - Jul 2007 - Combine R2HTML and Rcmd BATCH?

Hi All,

I have an R script that spawns output in the form of an HTML page. This 
is done by the R2HTML package.

Now I want to run the same script using Rcmd BATCH. However, it seems 
that it is not possible to use R2HTML in this case.

My script ends with this error message:
#########################
Error in dev.print(png, file = AbsGraphFileName, width = Width, height = 
Height,  :

can only print from screen device

Execution halted
#########################

I can not find how to work around this problem in the R2HTML manual or 
the help archives.

Has anybody done a similar thing before? Any suggestions?

Greetings,
Dieter

Dieter,

I use htmlize in library prettyR to produce a HTML report at the end of
a long batch file and this process works fine.  I posted my call to
htmlize below, but it would take too much modification for me to produce
a working example.  My guess is that it is something else that is
messing up the process.  I bet if you created a very simple example it
would work.  And if it didn't work, you could post it here and then
people could try to find out why it doesn't work.  If it does work, you
can add to it gradually until you find the problem.  This is how I got
htmlize to work.

Roger


library(prettyR)
today <- as.Date(Sys.time(), format="%m/%d/%Y")
htmlize(Rfile="//rinnycs0051/research/R_HOME/morningNotesMaster.r",
HTMLbase="morningNotes",
HTMLdir="//rinnycs0051/ramdata/morningNotes",
title="RAM Morning Notes " %+% today, echo=FALSE, do.nav=FALSE)

Hi Dieter,

There are two ways in R2HTML to work woth graphics.
- HTMLplot, that may require the interactive environment depending on how
you use it
- HTMLInsertGraph that is more suitable for batch scripting but requires
some more work.

First method:
HTMLplot and plotFunction (use print for trellis graphics). Not recommended.

Second method;
- Create the graphic in the format you need
- use HTMLInsertGraph to write HTML linking tag

Synopsis:

myGraphic <- file.path(outdir,"graph1.png")
png(file=myGraphic)
hist(rnorm(100))
dev.off()
HTMLInsertGraph("graph1.png",Caption="Graph1")

Do not hesitate to send me your file if more help is required

Best wishes,

Eric
