Dear R users,
I am trying to produce some plots in a postscript file, but I am
experiencing some issues. I open the device with
-----------------------------
setPS()
postscript (file='gs_mcmc_dust.ps',width=5*3,height=5*3,horizontal =
FALSE, paper = "special",family =
"ComputerModern",encoding="TeXtext.enc")#, onefile = FALSE
-----------------------------
(it's a 9x9 multiplot) and I close it with
-----------------------------
dev.off()
-----------------------------
Here are my problems:
-) xlab=expression(paste(lambda,"(",~mu,m,")")) : it correctly prints
the "mu" greek letter but it fails for the "lambda" letter, leaving a
blank space
-) text(min(mchain[2,]),max(tdensity$y),substitute( T[disk,med] == tmed
%+-% tstd (K),list(tmed=tmed,tstd=tstd)),pos=4,cex=1.5 ) : it prints
everything, but the "+-" symbol and "(K)" overlap with the substitute
for tmed and tstd respectively. How can I force a blank space between
numbers and symbols? Also, how can I set the number of decimal digits
for tmed and tstd? ( option(digits=4) does not work )
-) once I close the R session without saving it (I answer "n" when
quitting), the content of the ps file is erased. Do you know why?
I solve these problems plotting to a PNG device, but a postscript file
is what I need.
Can you help me, please?
Thank you very much in advance
Cheers
Gaetano
