It certainly does! Try col="transparent" (and perhaps consult your dictionary). It was news to me that the windows() graphics device worked on Linux i586. What it does not support as yet is translucent colours, and that is a restriction imposed by Windows (translucency support was introduced for Windows XP, and we still try to support older versions of Windows, unlike the MacOS people). I have been working on a workaround, so translucency support is likely to be implemented in R 2.6.0 for users of XP or later. Given that neither of the two main screen devices and neither of the standard print devices support translucency, the subject line looks correct to me: the problem surely lies in the assumptions made in ggplot2. > * export to a device that does support transparency (eg. pdf) > * use a solid fill colour : + stat_smooth(method="lm", fill="grey50") > > Hadley > > On 7/3/07, Stephane Cruveiller <[EMAIL PROTECTED]> wrote: >> Dear R-Users, >> >> I recently gave a try to the nice package ggplot2.
