Re: [R] Plotting multiple xyplots in same page

[Duncan Mackay]

Hi Lisa

have a look at par.settings in ?xyplot

trellis.par.get() shows the settings

trellis.par.get()[[27]]
$left
$left$tck
[1] 1

$left$pad1
[1] 1

$left$pad2
[1] 1


$top
$top$tck
[1] 1

$top$pad1
[1] 1

$top$pad2
[1] 1


$right
$right$tck
[1] 1

$right$pad1
[1] 1

$right$pad2
[1] 1


$bottom
$bottom$tck
[1] 1

$bottom$pad1
[1] 1

$bottom$pad2
[1] 1

as an example:

par.settings = list(
layout.heights = list(main = 0,
                      sub  = 0,
                      axis.top = 0.2,
                      top.padding  = 0,
                      bottom.padding = 0)    )

Dear Rhelp,

I was able to plot 6 figures in one page. I do need help in reducing the space between the title and the plot and assigning A,B,C,D,E,F to each figure

library(lattice)
trellis.par.set(theme = col.whitebg())
xy <- xyplot(decrease ~ treatment, OrchardSprays,
        main="Some plot",
              groups = rowpos, type = "a",
              auto.key = list(x = 0.2, y = 0.9,
                cex = 0.52, points = FALSE, lines = TRUE))


print(xy, pos = c(0.0, 0.5, 0.33, 1.0), more = TRUE)
print(xy, pos = c(0.33, 0.5, 0.66, 1.0), more = TRUE)
print(xy, pos = c(0.66, 0.5, 0.99, 1.0), more = TRUE)
print(xy, pos = c(0.0, 0.0, 0.33, 0.5), more = TRUE)
print(xy, pos = c(0.33, 0.0, 0.66, 0.5), more = TRUE)
print(xy, pos = c(0.66, 0.0, 0.99, 0.5), more = FALSE)

Thanks in advance,

Subject: Plotting multiple xyplots in same page

Dear Rhelp,

I would like to have 6 xyplots in the same page. Similar to (par(mfrow=c(3,3))

Found this example on the R archives.
library(lattice)
trellis.par.set(theme = col.whitebg())
xy <- xyplot(decrease ~ treatment, OrchardSprays,
              groups = rowpos, type = "a",
              auto.key = list(x = 0.2, y = 0.9,
                cex = 0.75, points = FALSE, lines = TRUE))

print(xy, pos = c(0.0, 0.0, 0.5, 0.5), more = TRUE)
print(xy, pos = c(0.0, 0.5, 0.5, 1.0), more = TRUE)
print(xy, pos = c(0.5, 0.0, 1.0, 0.5), more = TRUE)
print(xy, pos = c(0.5, 0.5, 1.0, 1.0), more = FALSE)




When I changed the print() to:

 print(xy, pos=c(0.0,0.0,0.33,0.33),more = TRUE),
the figure was not looking good.

Also, is it possible to assign A, B, C,D, etc for each figure.



a<- rnorm(1000,0,1)
b<- rnorm(1000,0,2)
c<- rnorm(1000,0,3)
d<- rnorm(1000,0,4)
par(mfrow=c(2,2))
hist(a,main="")
title(main="A",adj=0)
hist(b,main="")
title(main="B",adj=0)
hist(c,main="")
title(main="C",adj=0)
hist(d,main="")
title(main="D",adj=0)


I tried this to xyplot, but it was not working.

Please help me.

Many thanks in advance,
Lisa.
