Hi guys,to make it easier, here is a simple case with the same issues. I use the short function below to make the attached PS file.
Things to fix:-) the greek letter "lambda" is not printed, while "mu" is printed (see the plot command) -) the annotation inside the plot area: the "+-" symbol and "(K)" overlap with the substitute for tmed and tstd respectively (see the text command). Also, how can I set the number of decimal digits for tmed and tstd? (option(digits=4) does not work )
Moreover, I'd like to make the characters thicker. Is there any way? Finally, once I close the R session without saving it (I answer "n" when quitting), the content of the ps file is erased. Do I miss something in writing the function?
Thanks
Gaetano
