Thanks Jim,
The picture width is adjusted. That was great help! I really appreciate it.
Does lwd mean 'line width'? I'm not exactly sure how that will help. Can
you please explain the intuition behind it?
Can I also ask another question? My graph is made from 7 plots from
sm.density.compare(). These 7 plots are put together by:
par(mfrow=c(4,2))
To make all 7 plots comparable, I specify y- and x-axis ranges. Here is
the sample code for one of the plots:
sm.density.compare(
c(sample_1, sample_2), # sample_1 and sample_2 are two
vectors, each corresponding to a sample
rep(1:2, rep(140, 2)),
lty = c(1, 3),
lwd = c(1, 3), # This change was made by taking your
suggestion.
col = c("black", "black"),
xlab="Sample",
xlim=c(-40, 60),
ylim=c(0, 0.15)
)
legend("topright", c("MMNL", "GMNL"), lty = c(1, 3), cex = 1)
Somehow, xlim and ylim do not have an effect. I did not have this
problem when I was running R in Arch Linux; but now I'm using Debian Linux.
Thanks!
Kind regards,
Xianwen

Dear fellows,
The two questions are on sm.density.compare(). I compare kernel density
estimates of two arrays of data.
I'd like to scale up y-axis so that I can show better the differences in
y values. English is not my first language so I'll try to explain it. I
would like to stretch y-axis a bit longer but not to change the range of
y values. How can I do this?
Second, I'm using a solid line for one array of date and a dashed line
for another array of data. The difference is not easy to see, because
the two curves are approximate to some degree. Is it possible to plot
one array of data with *, instead of dash?
Hi Xianwen,
You can specify the width and height of the graphics device:
dev.new(height=9)
OR
png("myplot.png",height=600)
or some other type of device. This will produce a plot that is
noticeably higher than it is wide. For the second question, try:
lty=3,lwd=3
Jim
