R help - May 1998 - R-beta: par

I started using R to draw different plots. Thereby I'm having different
problems adjusting graphical parameters.
I wonder wy, because I don't see any reason. I'm using R61.1 with Linux
Slackware (kernel 2.0?), emacs19.31 and ESS-5.0

1. I want to write a text on margin-site 4, therefore I need to reduce my plot
in size . But
whatever I do, the size doesn't change:

postscript("a.ps")
a_c(1:10)
b_a*a
a
b
plot(a,b)
dev.off()
postscript("b.ps")
plot(a,b,mar=c(5,5,5,5))
axis(4,  labels = F, tck = 0.1)
mtext("blabla", side = 4, line = 3, cex=1.5)
dev.off()

"b.ps" does not have a different plot-size and therefore the label
"blabla" cannot be drawn.

2. In a log="x" plot, labels are drawn in exp.mode: 1e-02, 1e-01,..
   How can I change it to 0.01, 0.1, ... ?

3. If I want to write with latin-font in S-plus, I use 
   
   ps.options (paper="A4", setfont=ps.setfont.latin1)
   and ESS/emacs to write d,..
   
   With R the ps.opt.-command gives an error.
   Which is the correct way to do it?

thanks

Some of your problems should be gone
once you upgrade to  0.61.3 (instead 0.61.1).

0.61.2 und xx.3 have explicitly been  Bug-fix releases  
``that everybody should install'' (:-)   --- of course, not really)

You can work with
	axes = FALSE
and later explicit

	axis(1, at = ..., labels= ...)
	axis(2, at = ..., labels= ...)

Here is an example ((which also exhibits a long standing bug for
pch="."
		     AND a bug in 0.62 [no ticks !!]))

##--- Log-Log Plot  with  custom axes
lx <- seq(1,5, length=41)
yl <- expression(e^{-frac(1,2) * {log[10](x)}^2})
y <- exp(-.5*lx^2)
op <- par(mfrow=c(2,1), mar=par("mar")+c(0,1,0,0))

plot(10^lx, y, log="xy", type="l", col="purple",
     main="Log-Log plot", ylab=yl, xlab="x")

plot(10^lx, y, log="xy", type="o", pch='.',
col="forestgreen",
     main="Log-Log plot with custom axes", ylab=yl,
xlab="x",
     axes = FALSE, frame.plot = TRUE)

axis(1, at = my.at <- 10^(1:5), labels = formatC(my.at))
at.y <- 10^(-5:-1)
axis(2, at = at.y, labels = formatC(at.y))
par(op)
