I noticed that congigure reported libpng as "not found" although a recent version exists. Further looking into this issue told me, that the test failed because the test from R.m4 AC_CHECK_LIB(png, png_create_write_struct, [ BITMAP_LIBS="${BITMAP_LIBS} -lpng -lz" AC_DEFINE(HAVE_PNG) ], , ${LIBS}) ], AC_MSG_RESULT([no])) ]) did fail: gcc.exe -o conftest.exe -g -m486 -Zmt -Ig:/include -I/xfree86/include -Zmt -Zcrtdll -Zsysv-signals conftest.c -lpng -lsocket -lreadline...

Hi, I have been using the persp() function to plot species response surfaces based on GAMs (using package mgcv). Everything works fine, except that I have a slight problem when it comes to producing a figure with multiple (4 - 6) persp() plots on it. The axis labels remain the same size, no matter how large or small the plot is, causing some overlap when the multiplot figure is produced. Is

Dear R devel list, Good morning; I'm with the Sage (http://www.sagemath.org) project. (Some of you might have seen my talk on this at last summer's useR conference). We have some rudimentary support for using R graphics in various cases, which has proved useful to many of our users who want to go back and forth between R and other capabilities within Sage. Unfortunately, the way we
