I have a quick question about the browseURL function. When I use the function in
a UNIX environment, I have to use two sets of quotations if I have the &
symbol in the URL. For Windows I only need to use the first set. For example, on
Windows:
browseURL("http://search.yahoo.com/search?p=Bioconductor&ei=UTF-8&fr=fp-tab-web-t&n=20&fl=0&x=wrt")
will call up the appropriate website. However, if I use the same command under
UNIX, the website will be truncated after the first &, but the call will
work if I use:
browseURL("'http://search.yahoo.com/search?p=Bioconductor&ei=UTF-8&fr=fp-tab-web-t&n=20&fl=0&x=wrt'")
Where I have added single quotes around the URL.Is there any quick method for
solving this problem? Thank you very much for your help.

The problem is the interpretation by the shell used on Unix: on Windows no
shell is used. It seems to me that the Unix version of browseURl should be
quoting `url' in
remoteCmd <- if (isLocal)
switch(basename(browser), "gnome-moz-remote" = , open = url,
galeon = paste("-x", url), kfmclient =
paste("openURL",
url), netscape = , mozilla = , opera = , {
paste("-remote \"openURL(",
gsub("([,)])", "%\\1",
url), ")\"", sep = "")
})
else url
either by escaping & by \ or surrounding it by single quotes.
I can't see a simple solution for you with the present R codebase.

One way to avoid this problem is to create a one line javascript
file which redirects to your url. That way the shell never
gets its hands on your url. After setting the url:
url <-
"http://search.yahoo.com/search?p=Bioconductor&ei=UTF-8&fr=fp-tab-web-t&n=20&fl=0&x=wrt"
Run these three lines of code (only tested on Windows/IE):
cat( "<script language=", "javascript",
">location=",
url, "</script>\n", sep="\"",
file="temp.htm" )
browseURL("temp.htm")
unlink("temp.htm")
