Hello all,
Working with a typical xyplot figure (for example the first from
example(lattice) )
I would like to place the tick marks inside the panels instead of outside.
I believe working with the axis argument might be the way to do it, but do not
see how?
Could anyone help me out in doing this
Hello R-helpers,
I would like to produce a boxplot for dates, using lattice.
Here is a dummy example :
dates<-as.Date(32768:32895,origin="1900-01-01")
plouf<-data.frame(days=dates,group=factor(rep(1:2,times=128/2)))
bwplot(group~days,data=plouf)
# doesn't work, whereas :
bwplot(group~as.num
Hello all,
I have a question on bpplot (or more specifically panel.bpplot used with
bwplot) from package Hmisc.
I would like to produce a box-percentile plot but vertically. And I hqve not
been able to use the horizontal argument...
using one of the examples from ?panel.bpplot :

R-helpers,
I'm having difficulty with customizing strip names for a lattice graphic.
Here is an example using the iris data set :
xyplot(Sepal.Length+Sepal.Width~Petal.Length,groups=Species,data=iris)
## I'd like to change the 2 strip names to "Length" and "Width" for example,
this is what
st(at=mean(x),relation="free")))
I would have liked one tick at the mean of the x values in each panel... Which
isn't what I obtain. How do I customize the location of the tick marks for each
panel ?
Thanks again.
David

Hello R-helpers,
I'm writing a long function in which I manipulate a certain number of datasets.
I want the arguments of said function to allow me to adapt the way I do this.
Among other things, I want my function to have an argument which I will pass on
to subset() somewhere inside my functio
Hello all,
I was wondering if there is a package in which someone would have created a
quantile function that handles vectors of class "Date".
In advance thanks.

Hello,
I'm trying to pull off a certain graph using splom, and can't quite get my
panel functions right.
Basically, the equivalent using pairs would be something like this (using iris
data set as an example):
panel.corval <- function(x, y, digits=2, prefix="", cex.cor,col,pch)

R-helpers,
A quick question regarding my wanting to run multiple regressions without
writing a loop.
Looking at a previous discussion :
http://tolstoy.newcastle.edu.au/R/e2/help/07/02/9740.html
my objective is to do the "opposite", i.e. instead of having the same
independent variable and testi
s one dependent variable.
Best regards,
David Gouache

Hi
If you do not insist on matrix and use data frame instead
lapply(iris4,function(x) lm(iris$Sepal.Length~x))
can do it

Hello,
This may sound crazy, but I have a large number of Multiplan data files I'm in
the process of recuperating, and I'm hoping to avoid having to open them one by

if someone somewhere had encountered this and maybe
Hello all,
I have a large data frame and I want to look at the distribution of each

I'd like to do so using lattice.
