I'm trying to get help to print the help pages in html format to the terminal. This is in order to be able to see the html help files remotely.If I do printURL = function(file) {a=readLines(url(file));cat(a,sep="\n")} options(browser=printURL) options(help_type="html") then invoking help with ?print gets stuck. I think what happens is that the web server run by R that allows one to read help will not work as long as R is waiting for the function to complete. Thus, if I run a second R session, and try to read the help files that one session produces from the other, I have no problems. I also tried options(browser="wget -O- ") But again, while R is waiting for the command to complete, the web server is dead. Is there a better way to accomplish this?
What you're doing should work, and it works for me in 2.11.1 in Windows. Not sure why it doesn't work for you.
A more direct way to get the HTML output for a help file is to use the internal utilities that R uses. You get the help page using
page <- utils:::.getHelpFile(?print) (remember to keep that question mark!), and use tools::Rd2HTML(page) to turn it into HTML.
