The problem is a bit weird.
This does not work:
ps.options=setEPS()
postscript(file="exponcoverapprox.eps")
boxplot(test[30,1:500],test[90,1:500],test[150,1:500],test[210,1:500],test[270,1:500],test[330,1:500],test[390,1:500],names=c("1","3","5","8","10","13","1"),outline=FALSE,ylim=c(0.01,50),log="y",
xlab = "xvalue",ylab="yvalue",boxwex=0.5, pars
=list(whisklwd=0,staplelwd=0))
dev.off()
This works
postscript(file="exponcoverapprox.eps")
boxplot(test[30,1:500],test[90,1:500],test[150,1:500],test[210,1:500],test[270,1:500],test[330,1:500],test[390,1:500],names=c("1","3","5","8","10","13","1"),outline=FALSE,ylim=c(0.01,50),log="y",
xlab = "xvalue",ylab="yvalue",boxwex=0.5)
dev.off()
To not bother you with the details, the only difference is the pars
=list(whisklwd=0,staplelwd=0) at the end of the boxplot , which I use to remove
the whiskers fromt he blot.

You did not create an EPS file. See ?postscript and pay attention to the fourth
paragraph under Details:
The postscript produced for a single R plot is EPS (Encapsulated PostScript)
compatible, and can be included into other documents, e.g., into LaTeX, using
\includegraphics{<filename>}. For use in this way you will probably want to use
setEPS() to set the defaults as horizontal = FALSE, onefile = FALSE, paper =
"special". Note that the bounding box is for the device region: if you find the
white space around the plot region excessive, reduce the margins of the figure
region viapar(mar=).
