Apparently so: this will be fixed in R-patched shortly.
Thanks for the report.

Hi,
I don't know if I am the first one to report the problem:
in 2.8.0 dev2bitmap gained aa support, but "extra" is null
if neither taa nor naa is specified.
dev2bitmap("plot.pdf",type="pdfwrite")
Error in paste(shQuote(gsexe), " -dNOPAUSE -dBATCH -q -sDEVICE=", type, :
object "extra" not found
dev2bitmap("plot.pdf",type="pdfwrite",taa=4)
I guess a useful default for extra is missing:
if (!is.na(taa))
extra <- paste(" -dTextAlphaBits=", taa, sep = "")
if (!is.na(gaa))
extra <- paste(extra, " -dGraphicsAlphaBits=", gaa, sep = "")
cmd <- paste(shQuote(gsexe), " -dNOPAUSE -dBATCH -q -sDEVICE=",
type, " -r", res, "-dAutoRotatePages=/None", " -g", ceiling(res *
width), "x", ceiling(res * height), extra, " -sOutputFile=",
shQuote(file), " ", tmp, sep = "")
best wishes,
ido
