Hello
Thank you for the advice on vector.
I found a previous mail on this issue and pasted it below.
Now here comes a different scenario.
I have more than 20 boxplots and just wanted the first two from the left to
be red and the rest to be blue.
Please kindly advise how to code the color without writing the color names
18 times.
Thanks again.
Elaine
code for color using vector
dataset <- data.frame ( time = rep(1:5,times=9),
genotype = factor(rep(rep
(c("A","B","C"),each=5),times=3 )),
location= factor(rep (paste("LOC",1:3),each=15)),
color = rep (rep
(c("red","green","blue"),each=5),times=3
),
result = rnorm (45))
library(lattice)
# The black, red, green behaviour you were seeing is because
# dataset$color is a factor
dataset$color
# which is coded 1, 2, 3 levels = ("red", "green", "blue").
# This is being interpreted as the first three colours of the palette
pallete()
# coerce the vector to a character vector
as.character(dataset$color)
# gives you
xyplot( result ~ time | location, data=dataset,groups=genotype,
fill.color = as.character(dataset$color),
panel = function(x, y,fill.color,...,subscripts) {
fill = fill.color [subscripts]
panel.xyplot(x, y,pch=19, col=fill, type ="b")}
)
# Lines only take a single value so only the first value of the vector,
# "red", is passed to line colour.
# these are simple alternatives
xyplot( result ~ time | location, data=dataset, groups=genotype,
pch=c(1,2,3), type="b",
col=c("red","blue","green"))
xyplot( result ~ time | location, data=dataset, groups=genotype,
pch=c(1,2,3), type="b",
col=dataset$color)
# or use
par.settings <- list(superpose.symbol = list(col = c("red", "green",
"blue"), fill = c("red", "green", "blue")), superpose.line = list(col =
c("red", "green", "blue")) )
xyplot( result ~ time | location, data=dataset,groups=genotype,pch=19,
type = "b", par.settings = par.settings)
