Hello!
I want to display four xyplots in the same window (sorry if I don't use the
propers words, but my English is rude)
I know that if I use plot(y~x) then
x=(1:100)
y=(1:100)
par(mfrow=c(2,2))
plot(y~x)
plot(y~x)
plot(y~x)
plot(y~x)
would give what I want, but this is not the case because I need the functions
of xyplot.
So I did the following:
plot.new()
title(main="Tasas de Mortalidad por 100.000 habitantes",outer=TRUE)
print(xyplot(y~x), position=c(0,0.5,0.5,1), more=T)
print(xyplot(y~x), position=c(0.5,0.5,1,1), more=T)
print(xyplot(y~x), position=c(0,0,0.5,0.5), more=T)
print(xyplot(y~x), position=c(0.5,0,1,0.5), more=T)
In the output the title is not complete, a part of the letters only is seen.
I searched how to solve this problem but nothing worked.
I don't know why you need xyplot, but an easy solution
would be to create a factor variable and then plot
y ~ x conditional on the factor:
dat <- data.frame(x = rep(x, 4), y = rep(y, 4), g = gl(4, 100))
xyplot(y ~ x | g, data = dat, main = "whatever you want")
If you want separate axes with possibly modified interpanel
spacing and with/without the strips:
xyplot(y ~ x | g, data = dat
,main = "whatever you want"
,strip = FALSE # remove if you want the strips
,between = list(x = 1, y = 2)
,scales = list(relation = 'free', rot = 0)
)
Another possibility might be the latticedl package, but I
haven't yet used it.

I read about "figure margins", proved with different things like oma, omi, mar,
mai,layout, par, mfcol, mfrow,mtext,title...
I hope you can guide me!
Thanks a lot!
