Dear Nevil, Converting your pdf to png will be the most efficient way to reduce the file size with scatter plots.
You can either export directly to pdf or first create a pdf and then use ghostscript to convert it into png. I tend to the the latter because it is easier to get plots with a consistent layout. The convertion can be done within R. See the code below. system("C:/Progra~1/gs/gs8.64/bin/gswin32 -r300 -dSAFER -dBATCH -dNOPAUSE -sDEVICE=png16m -dGraphicsAlphaBits=4 -sOutputFile=fig_Power_Resid.png fig_Power_Resid.pdf") HTH, Thierry ------------------------------------------------------------------------ ---- ir.
