Hi Anna
I am still unsure what you want
1 do you want 1 panel or 3?
2 do you want 1 y axis on the left and 1 on the right
or 1 y axis on the left and 2 on the right
or 1 on the right varying with
groups in a multipanel plot
For starters try
xyplot(Value ~ Year, mydata, groups = Type,
allow.multiple = T,
distribute.type = TRUE,
par.settings = list(layout.heights = list(key.top = 1.5)), #
separate key from bottom a bit more
col = c("black","black","black"), # for points
key = list(text = list(label = c("stuff1","stuff2","stuff3")),
lines = list(col = 1:3),
cex = 0.8,
title = "stuff type",
cex.title = 0.9,
space = "bottom"),
subscripts = TRUE,
panel = panel.superpose,
panel.groups = function(x, y, subscripts, ...,group.number) {
panel.xyplot(x, y, ...)
panel.xyplot(x, mydata[subscripts,"mavg"], col =
c(1:3)[group.number], type = "l")
})
OR
xyplot(Value ~ Year|Type, mydata,
allow.multiple = T,
aspect = 0.75,
layout = c(1,3),
groups = Type,
distribute.type = TRUE,
par.settings = list(layout.heights = list(key.top = 1.5)), #
separate key from bottom a bit more
scales = list(alternating = F),
col = c("black","black","black"),
subscripts = TRUE,
key = list(text = list(label = c("stuff1","stuff2","stuff3")),
lines = list(col = 1:3),
cex = 0.8,
title = "stuff type",
cex.title = 0.9,
space = "bottom"),
panel = panel.superpose,
panel.groups = function(x, y, subscripts, ...,group.number) {
panel.xyplot(x, y, ...)
panel.xyplot(x, mydata[subscripts,"mavg"], col =
c(1:3)[group.number], type = "l")
})
have a look at
?lattice::axis.default
for yscale.components
This means that you only need 1 xyplot object
if you use doubleYScale you need to xyplot objects
1 for the points and another for the averages
These are then superimposed with the doubleYScale
Also read and re read ?xyplot
names(trellis.par.get()) give you a list of the names in trellis.par.get()
and trellis.par.get() gives you all the settings used by argument
par.settings in xyplot and those in the lattice series
par.settings may help you with themes.

Subject: RE: [R] lattice, latticeExtra: Adding moving averages to double y
plot
Hi Duncan and many thank's for your help!
I could see your first message perfectly.
You solved my problem to some extent. What my problem is, is that I need a
double y plot with two of these moving averages belonging to one axis (both
are temperature measurements, say Stuff 2 and 3, measured in degrees C) the
other one reading off the second axis (a nutrient measurement in mM (say
Stuff1)).
How can I plot Stuff2 and stuff3 moving averages in one plot and stuff1 in
another and then combine them using doubleYscale?
I also have some other annotated questions regarding linetypes. I could
change symbols using pch, but not the line type. Why? See code below:
Many many thank's once again.
mydata<- data.frame(
Year = 1980:2009,
Type = factor(rep(c("stuff1", "stuff2", "stuff3"), each = 10*3)),
Value = rnorm(90, mean = seq(90),
sd = rep(c(6, 7, 3), each = 10)))
library(lattice)
library(latticeExtra)
stuff1data <- mydata[(mydata$Type) %in% c("stuff1"), ]
stuff2_3data <- mydata[(mydata$Type) %in% c("stuff2", "stuff3"), ]
# make moving averages function using zoo and rollmean:
library(zoo)
library(plyr)
f <- function(d)
{
require(zoo)
data.frame(Year = d$Year[5:length(d$Year)],
mavg = rollmean(d$Value, 5))
}
# Apply the function to each group as well as both data frames:
madfStuff1 <- ddply(stuff1data, "Type", f)
madfStuff2_3 <- ddply(stuff2_3data, "Type", f)
# Some styles:
myStripStyle <- function(which.panel, factor.levels, ...) {
panel.rect(0, 0, 1, 1,
col = bgColors[which.panel],

c(rep(NA,4), madfStuff1[,3], # what is rep(NA,4) doing?
rep(NA,4), subset(madfStuff2_3, Type== "stuff2",3, drop = T), # is "3"
referring to the number of factors?

# how can I add a legend specifying the linetype AS WELL AS symbol?

could not make it work.

I do not know what happened to my last email as this are set up as plain
text so I am sending the code again so I hope this works
I am not sure what you wanted exactly but this will plot the points and
lines of the average.
I have not worried about the 2nd axis
Here is one way of doing things by combining the averages into the
dataframe.
It makes it easier that way as you do not have to match up the x values
# combine averages into mydata
mydata$mavg <-
c(rep(NA,4), madfStuff1[,3],
rep(NA,4), subset(madfStuff2_3, Type== "stuff2",3, drop = T),
rep(NA,4), subset(madfStuff2_3, Type== "stuff3",3, drop = T))
xyplot(Value ~ Year, mydata, groups = Type,
allow.multiple = T,
distribute.type = TRUE,
col = c("red","blue","cyan"),
subscripts = TRUE,
panel = panel.superpose,
panel.groups = function(x, y, subscripts, ...,group.number) {
panel.xyplot(x, y, ...)
panel.xyplot(x, mydata[subscripts,"mavg"], col =
c("red","blue","cyan")[group.number], type = "l")
})

BTW libraries are case sensitive as well. Is it you editor putting capitals?

Subject: [R] lattice, latticeExtra: Adding moving averages to double y plot
Hi lattice users,
I would like to add 5-year moving averages to my double y-plot. I have three
factors needs to be plotted with moving averages in the same plot. One of
these reads off y-axis 1 and two from y-axis 2. I have tried to use the
rollmean function from the zoo-packages, but I fail in insering this into
lattice (I am not an experienced lattice user). I want to keep the data
points in the plot.
Find below dummy data and the script as well as annotations further
describing my question.
thank you in advance!
