[R] CGIwithR and visible output of 'invisible(capture.output(library(...)))'

Dear alltogether,

I want to use CGIwithR in conjunction with R2HTML.

A small example called 'test.R':


#! /usr/bin/R
HTML(summary(as.numeric(scanText(formData$numbers))), file=stdout())


The script gets its input via 'CGIwithR.cgi' and contains the variable

The 'HTML' output (-> summary() in this example) goes well, but the
loading of the R2HTML library is also printed (!) in the resulting html

As I took the example from the original CGIwithR examples and I also
read the manpages of invisible() and capture.output(), I do not find a
logical reason why this still happens.

Deleting the line with "invisible ... library().." and adding
'library(R2HTML)' to .Rprofile does not solve the problem.

I use ubuntu edgy, R Version 2.3.1 (2006-06-01)


best wishes,


PS: the output is (uncut)
