As I wrote earlier:
"I had to add the rectangles= and points= arguments to
auto.key to get the same key as you had earlier."
and the relevant line in the code was:
auto.key = list(space = 'right', rectangles=TRUE, points=FALSE)

Hello Peter and David,
Thanks for your help. I have added what you suggested and its working
perfectly fine except:
When I add the panel function, the legend changes. In the sense without the
panel function the column names are shown with small colored rectangles (on
right), but after adding it the rectangles change to tiny un-filled
diamonds. Any suggestions?
My current code and data is below,
Thanks a lot,
Peng
Data:
Sample Col1 Col2 Col3
Row1 -2 4 -1
Row2 3 -2 4
Row3 3 5 -2
Row4 4 1 -1
Code:
dta<-read.table("data.txt", header=TRUE, row.names="Sample")
coltemp=c(619,376,497)
myYscale <- seq(-10, 10, 1)
barchart(data.matrix(dta),
horizontal=FALSE,
stack=TRUE,
par.settings = simpleTheme(col = colors()[coltemp]),
auto.key=list(space="right"),
border=NA,
panel=function(x,y,...){
panel.abline(h=c(myYscale), col.line="gray")
panel.barchart(x,y,...)
},
scales = list(y = list(at = myYscale))
)
Thanks,
Peng

Hi Again,
Before I start getting into what you just suggested, let me confirm if I
made my point clear previously. I'm looking for horizontal lines similar to
one on the following link (It has parallel lines for each y=200, y=400,...):

What you just suggested can solve this purpose? Thanks,

Thanks David, I tried panel.abline(h=somevalue) -- both inside and

Here's some code related to the data you posted earlier.
barchart(data.matrix(dta), horizontal = FALSE, stack = TRUE,
par.settings = simpleTheme(col = 2:4),
panel=function(x,y,...){
panel.abline(h=c(-2,0,3,4), col.line="gray")
panel.barchart(x,y,...)
},
scales = list(y = list(at = -2:8)),
auto.key = list(space = 'right', rectangles=TRUE,
points=FALSE)
)
If you want the gray lines in front of the bars, switch the
order of the panel functions. With lattice, it's all about
what goes into each panel (you have only one panel here).
If you want more than one thing in a panel, you have to set
up a function to do those things.
I had to add the rectangles= and points= arguments to
auto.key to get the same key as you had earlier.

Thanks a lot Peter! One more help, is there a similar function
abline()
for
barchart().
?panel.abline
I'm trying to add a (light gray colored) horizontal lines, one for
each
y-value.

Hi Peter,
I'm not sure but it seems "scales" command works only with integer
values.
If the y-axis values are very small (such as -0.03, -0.02, -0.01, 0,
0.01,..., 0.08). My current plot has values 0, 0.05, and 0.10 only.
But
I
need it to extend it to negative numbers and reduce the scale width
(like
-0.04, -0.02, 0, 0.02,...).
Can I change these too? Thanks!
Use, e.g.
myYscale <- seq(-0.04, 0.08, 0.02)
barchart(...,
...,
scales = list(y = list(at = myYscale)),
...
)

Hi R Users,
I'm trying to plot a stacked barplot. Here is data:
Sample Col1 Col2 Col3
Row1 -2 4 -1
Row2 3 -2 4
Row3 3 5 -2
Row4 4 1 -1
I'm using following R code:
library(lattice)
dta<-read.table("data.txt", header=TRUE, row.names="Sample")
barchart(data.matrix(dta),
horizontal=FALSE,
stack=TRUE,
col=2:4,
auto.key=list(space="right",
title=names(dimnames(dta))[2])
)
Above code is working fine, but I need help with:
1) Legend boxes have default colors, whereas I'm looking them to
match
with
barplot colors (col=2:4).
replace the line
col = 2:4,
with
par.settings = simpleTheme(col = 2:4),
2) Can I increase scale for y axis, like currently it plotting
-2,0,2,4,...
I would like it as -2,-1,0,1,...
add the line
scales = list(y = list(at = -2:8)),
or whatever tick locations you prefer.

Any help would be greatly appreciated,
Thanks,
