I can confirm that using shell() directly on the .dvi file generated by
latex() works, while system() does not -- it hangs
as before.
However, Yihui's patch, in this form still hangs, so maybe there is
something else going on here.
`show.dvi` <-
function (object, width = 5.5, height = 7)
{
viewer <- optionsCmds("xdvi")
cmd <- if (viewer == "yap") {
paste(viewer, object$file)
}
else if (viewer == "kdvi") {
paste(viewer, object$file)
}
else if (viewer == "xdvi") {
paste(viewer, " -paper ", width, "x", height, "in -s 0 ",
object$file, sep = "")
}
else {
paste(viewer, object$file)
}
if (.Platform$OS.type == 'windows') system = shell
system(cmd, intern = TRUE, wait = TRUE)
invisible(NULL)
}
environment(show.dvi) <- environment(latex)
