barchart() {Lattice} -- auto.key()
Hi R Users,
I'm using following data/code (data is also attached) to produce a stacked
barplot.
*I need help with changing legend boxes, currently I'm using
"rectangles=TRUE". Is it possible to get small squares instead -- may be
with a small gap between colored squares.* Currently there is no gap between
the colored rectangles.
# Sample Data:
Names Col1 Col2 Col3
Row1 -20 40

Hi R Users,
I'm trying to plot a stacked barplot. Here is data:
Sample Col1 Col2 Col3

generating multiple sequences in subsets of data
I'm running into a problem I can't seem to find a solution for. I'm
attempting to add sequences into an existing data set based on subsets
of the data. I've done this using a for loop with a small subset of
data, but attempting the same process using real data (200k rows) is
taking way too long.
Here is some sample data and my ultimate goal

restricted bootstrap
Hello List,
I am not sure that I have the correct terminology here (restricted
bootstrap) which may be hampering my archive searches. I have quite a large
spatially autocorrelated data set. I have xy coordinates and the
corresponding pairwise distance matrix (metres) for each row. I would like
to randomly sample some number of rows but restricting samples such that the
distance between them is

Combine multiple tables into one
Hi,
May be this helps:
dat1<- as.data.frame(table1)
?dat2<- as.data.frame(table2)
names(dat2)<-c("V3","V4")

res<-join(dat1,dat2,type="full")
?res[is.na(res)]<- 0

panel function with barchart (lattice)
Folks at R help,
I can't quite get the panel function to work the way I
want within barchart.
I guess I'm still not understanding how to piece
together multiple panel
arguments, especially when "groups" is specified.
Example: I want to be able to add the value of "yield"
to each section of
each bar in this graph:
barchart(yield ~ variety | site, data = barley,

re-ordering x-lables using barchart()
Hi R Users,
I'm trying to re-order the "site names" ("Waseca", "Morris", ...). I'm using

Dropping rows conditionally
Dear R-help team,
I am getting addicted to using R but keep on getting many challenges on the way especially on data management (data cleaning).
I have been wanting to drop all the rows if there values are `NA' or have specific values like 1 or 2 or 3.
mdat <- matrix(1:21, nrow = 7, ncol=3, byrow=TRUE,

How to sort a grouped barchart?
Hi,
I have a barchart very similar to the example on the function documetation,
however, I want to sort the bars according one group in one panel.

groups = year, layout = c(1,6),
ylab = "Barley Yield (bushels/acre)", auto.key=list(),

How to use: library lattice: barchart
Dear ladies and gentlemen!
In the help text for the xyplot (library(lattice), help(xyplot)) is an example
given how one can use barchart:
barchart(yield ~ variety | site, data = barley,
groups = year, layout = c(1,6),
ylab = "Barley Yield (bushels/acre)",
scales = list(x = list(abbreviate = TRUE,

Removing inter-bar spaces in barchart
Rhelpers:
I'm trying to make a barchart of a 2-group dataset
(barchart(x~y,data=data,groups=z,horizontal=FALSE)). My problem is
that I can't, for the life of me, seem to get rid of the inter-bar
space -- box.ratio set to 10000 doesn't do much. Any ideas? I'd
ideally want zero space between the bars. Thanks!

update matrix with subset of it where only row names match
I guess this has a simple solution:
I have matrix 'mat1' which has row and column names, e.g.:
A B C
row1 0 0 0
row2 0 0 0
....
rown 0 0 0
I have a another matrix 'mat2', essentially a subset of 'mat1' where the
rownames are all in 'mat1' e.g.:
B
row3 5
row8 6
row54 7
I want to insert the values of matrix mat2 for column B (in reality it
could be some or

adjusting levelplot color scale to data
Hi guys,
I have a matrix with values varying from approximately -0.7 to 0.33 that I
want to create a heatmap/levelplot with.
When I execute the levelplot function for my matrix, I end up getting colors
that are adjusted to the max and min rather than around 0. In other words,
ideally I would like to have a color ramp that goes from red (negative
number), to white (0), to blue (positive);

Rotating the axis labels in the basic graphic device ?
Hello dear R help group,
I learned recently that one can change the rotation of labels in the axis,
when using a lattice plot, for example:
library(lattice)
barchart(yield ~ variety , data = barley,
groups = year,
ylab = "Barley Yield (bushels/acre)",
scales = list(rot = 45))
My question is: Is there an application of "rot" in something like

converting a data-frame by a defined rule
Hi,
I have a data frame with several columns.
Now I want to transfer the data into a new variable (also a data
frame), but I only want a part of the data, defined by a rule ...
for example; I have following data frame:
row1 row2 row3
x 2 3
x 1 4
y 5 3
y 2 3
I know want a data frame, only with lines containing x in row1.
I know how to do that for one row (f <-

how to reorder of groups and specify ylim for each row in lattice barchart
R experts,
Is there anyway to reorder inside each group? In the following example, the
bar of year 1932 is always plotted before the bar of year 1931, may I change
the order inside each groups of bars?

Color cells of a matrix as in Excel
All,
I frequently make spreadsheets in Excel in which I rank values in columns
by stop-light colors (red is bad, yellow is OK, green is good).
Image and heatmap expect a matrix in which all the data are in the same
scale, but I frequently have different scales in different columns. ie.
Column one runs from 1-10 while column 2 runs from 1-100. I thus need to
define a separate color ramp for each

Creating named.list from two matrix columns
Hi Friends,
I am new to R.
On R utility class pages, creating "named.list" is described with this command :
new("named.list",a=1,b=2)
For large matrix having two columns, such as :
"row1" 2334
"row2" 347
"row3" 379
...
I want to create a named.list like :
$row1
[1] 2334
$row2
[1] 347
...
Can anyone explain how "named.list"
