Lattice : factor levels in the margins
Hello !
I'm struggling again against lattice graprhics. ;) I'm trying to produce
a conditionnal xyplot with two conditionning factors (let's say A and
B). I want the levels of those factors (A1, A2, etc) to show in the
margins of the lattice plot, not in the strips between the panels.

Creating a factor from a combination of vectors
Dear list,
Here's a little problem I already solved with my own coding style, but I
feel there is a more efficient and cleaner way to write it, but had no
success finding the "clever" solution.
I want to produce a factor from a subset of the combination of two
vectors. I have the vectors a et b in a data-frame :
> df <- expand.grid(a=c(0, 5, 10, 25, 50), b=c(0, 25, 50,

I'm stuck with a little graphical problem. I'm generating several

Line width in graphs
Hi,
I'm using R to plot some data and associated linear models, and I was
wondering if there was a parameter to fix the line width in the graphs (for
axis, lines, ...) because I explored the associated help pages and could
not find it.
Thx in advance,

randomForests predict problem
Hello everybody,
I'm testing the randomForest package in order to do some simulations and I
get some trouble with the prediction of new values. The random forest
computation is fine but each time I try to predict values with the newly
created object, I get an error message. I thought I was because NA values

drawing ellipses

First I want to thank all the people who answered my question about line

the end of the month !

to trace circles with 'symbols()', but no ellipse. I'm planning on writing

vector of center of
Hello
I have a vector gd of 279 values of diameter of limpets.
Using 'hist(gd, breaks=seq(10,60,5),plot=F)' I can obtain a vector of
10 centers of size-class ($mids).
But I'd like to work on a vector of 279 values being the mids (centers
of size-classes) corresponding to the respective 279 values in gd.

xyplot - help with multiple Y's vs. X of a member data in multiple panels
Dear R experts,
Wish you all a HAPPY NEW YEAR!
How do I go about plotting (using lattice) overlays of an ID (group=ID)
observed, fitted data in each panel of a multiple panel plot (each panel
identified by DS1 + DS2 + DS3)? "x" variable is X1 in the accompanying
section of a dataset. each individual is identified by color and Y's are
identified by "pch" or "lty".

simple test on slope of lm()
Hello
I want to compare the slope (let's say 'b') of a linear model obtained
with lm() to a theoretical value (let's say 'th').
To do so, I think I should compute a 't value' using
something like :
(b - 'th')/standard.deviation(b)
and then look at the p-value of this computed t.
I don't understand how to do this in a simple way, just using lm()

All other variables in upper scope arg for stepAIC
Hi - I am trying to substitute for "the_other_y" in the code below. I want
y2 and y3 to be there when i is 1, y1 and y3 to be there when i is 2 and y1
and y2 to be there when i is 3. I'm sure it's to do with what format the

of alldata except i rather than each column one at a time. I've tried

lattice/xyplot: plotting 4 variables in two panels - can this be done?
Hi,
I would like to create a plot of y1,y2,y3,y4 against x for several subjects such that y1 and y2 are plotted against x in one panel and y3 and y4 against x in another panel. Thus if there are 3 subjects I should end up with 6 panels. Is there a simple way of doing so (i.e. without calling xyplot() several times, and then padding the results together)??

Calling update on an lm-object inside a function
Dear all,
I want to update an lm (or glm) object by changing the response variable and I want to do so inside a function. Doing the update outside
of a function is straight forward:
x <- 1:5
y <- c(1,2,3,3,6)
mm <- lm(y~x)
y2 <- c(1,3,3,4,6)
mm2<- update(mm, y2 ~ .)
But I want to make the update inside a function (where the new response variable is declared

Using a loop to define new variables
Hi,
I'm a novice R user, much more used to SAS. My problem is pretty simple - basically, in a data frame, I have variables named
x1,....,x10 and y1,...,y10; and I would like to create r1 = x1 / y1 etc
Apologies if this is way too rudimentary - but I couldn't find any posts online which solve this exact issue.
