Dear all It seems that it is not possible [1] to generate several graphs in a loop within an Sweave document. For example, <<fig=TRUE>> for (i in 1:4) plot(rnorm(100)+i) @ will not work. Since this limitation dates from old times (at least 2005), I was curious whether workarounds other than "\includegraphics{}" appeared in meantime. Perhaps something related to cacheSweave or pgfSweave? If you are aware of any such hacks, please post them here. Regards Liviu [1] http://www.stat.uni-muenchen.de/~leisch/Sweave/FAQ.html#x1-11000A.9
