Descriptive Stats from Data Frame
I don't find how to do what I need to do in Dalgaard or 'R Cookbook', so
I'm asking here.
I have a data frame with water chemistry data and I want to start
exploring these data. There are three factors (site, date, chemical)
associated with each measurement. The data frame looks like this:

Repeated Measures, groupedData and lme
Hello
I am trying to fit a REML to some soil mineral data which has been
collected over the time period 1999 - 2004. I want to know if the 19
different treatments imposed, differ in terms of their soil mineral
content. A tree model of the data has shown differences between the
treatments can be attributed to the Magnesium, Potassium and organic
matter content of the soil, with Magnesium being the

bwplot questions: box order, axis breaks, and multiple y-axis labels
Hi all,
I used bwplot in lattice to create a 6-panel boxplot grouped by a
conditioning variable (param) that displays concentration (conc) in
response to treatment (trtmnt). Here is the functional part of my
code followed by my three questions:
library(lattice);
ww<-read.csv(file="c:/Rdata/lattice_boxplot_prep.csv",header=TRUE,sep=",");

bwplot in ascending order
Can anyone point me to examples with R code where bwplot in lattice is used to order the boxes in ascending order? I have found the following discussion and it partly works. But, I have a conditioning variable, so my example is more like
bwplot(var1 ~ var2|condition, dat)
Th example in the discussion below works only when there is not a conditioning variable as far as I can tell. I can tweak the

alternative to 'groups' for lattice bwplot()
Hi,
Is there some alternative to the 'groups' argument in lattice's bwplot
function for boxplots? Say in the example below:
bwplot(yield ~ site | year, data = barley)
you want to have two side by side boxplots per site, corresponding to each
year in the barley data frame. Ideally, the space between boxplots of the
same site should be smaller than that between boxplots of different

Optimization in R similar to MS Excel Solver
Dear Colleagues,
I am attempting to develop an optimization routine for a river suspended
sediment mixing model. I have Calcium and Magnesium concentrations (%) for
sediments from 4 potential source areas (Topsoil, Channel Banks, Roads,

magnesium concentrations, what are the optimal contributions from each

bwplot(): Can Panel Heading Span Two Lines?
A conditioning factor for bwplot() is the stream name. There are 17
streams so each panel is comparatively small and the names in the panel
header are truncated at both ends. I would like to wrap the names on two
lines for each panel but do not see if this can be done when I look at the
online docs (?bwplot) or the Lattice book. Is there a way to fit long
strings as headers with multiple panels on

Colour filling in panel.bwplot from lattice
Inspired by colouring the dots of box-whisker plots I am trying to also
fill the boxes (rectangles) with different colours. This seems not to
work as I expected.
Looking at the help page of panel.bwplot it says: 'fill - color to fill
the boxplot'. Obviously it is only intended to fill all boxes with only
one colour?
Nevertheless the following example shows, that 'fill' from

turn off selected axes in bwplot
I want to turn off selected axes in bwplot. I would like to only have the bottom axis drawn, with the others off.
I have a series of bwplots that I want on one device, like this:

p2<-bwplot(x2,box.ratio=.1)

Lattice::bwplot unexpected behaviour when using vector of colors
Hi,
I'm trying to produce colored boxplots using lattice::bwplot function. I need to plot each boxplot in the panel with a specific color. Naturally I used a vector of colors and expected to see colored boxplots. Although the boxplots were colored, the color of whiskers and the boxes do not match. Here is an example:
