I guess that is hard-coded in Sweave, so you probably cannot control
it unless you (partially) rewrite the driver. And just FYI, you can
try the knitr package, which does not add the hyphen for you, but the
name of the option 'prefix.string' has been changed to 'fig.path'
(http://yihui.name/knitr/options). If you set fig.path='foo/', figures
will be generated as, e.g., foo/label.pdf instead of foo/-label.pdf
utils::RweaveChunkPrefix
function (options)
{
if (!is.null(options$label)) {
if (options$prefix)
chunkprefix <- paste(options$prefix.string, "-",
options$label, sep = "")
else chunkprefix <- options$label
}
else chunkprefix <- paste(options$prefix.string, "-",
formatC(options$chunknr,
flag = "0", width = 3), sep = "")
chunkprefix
}
