Hi R experts,
I'm using the xyplot function in lattice to draw a multipanel plot consiting
of 5x6 scatterplots.
Now I need to link single points in each of those scatterplots (=panel),but
the points, that need linking are different for each panel.
I tried to use the panel.segments function for that, but I can't address
each panel separately. Links right for panel 1, show up in all other panels,
too. Tried functions like [panel.number()], but didn't work.
Would be so great, if somebody could help me with that!
That's the code, I used:
library(lattice)
library(latticeExtra)
#[...]
attach(mydata)
attach(links) #containing the coordinates for the segments fx, fy, tx, ty
fx <- fx
fy <- fy
tx <- tx
ty <- ty
xyplot(LogN~LogM|factor(surber),
par.settings = list(strip.background = list(col = "transparent")),
xlab = "Log M", ylab = "Log N",
layout = c(6,5), aspect = 1, as.table = TRUE, strip=FALSE,
panel=function(x,y){
panel.xyplot(x,y,pch=20,col="black", bg="transparent")
panel.fill(col = "transparent")
panel.segments(fx,fy,tx,ty[panel.number()])
})
Also tried to split the data and loop it (but this code might be a bit
messy. Apologies!) sn is the variable used to split according to panel. I
just tried to do the links for 2 panel here:
fx <- split(links$fx,links$sn)
fy <- split(links$fy,links$sn)
tx <- split(links$tx,links$sn)
ty <- split(links$ty,links$sn)
sn <- sn
dothese <- c(1,2)
ct <- 0
for (i in dothese){
ct <- ct + 1
x1 <- fx[[i]]
y1 <- fy[[i]]
x2 <- tx[[i]]
y2 <- ty[[i]]
}
xyplot(LogN~LogM|factor(surber),
par.settings = list(strip.background = list(col = "transparent")),
xlab = "Log M", ylab = "Log N",
layout = c(6,5), aspect = 1, as.table = TRUE, strip=FALSE,
panel=function(x,y){
panel.xyplot(x,y,pch=20,col="black", bg="transparent")
panel.fill(col = "transparent")
panel.segments (x1,y1,x2,y2 [panel.number(1,2)])
})
Thanks, Doris
