Hi, I am using clogit() from survival package to do conditional logistic
regression. I also need to make prediction on an independent dataset to
calculate predicted probability. Here is an example:
> dat <- data.frame(set=rep(1:50,each=3), status=rep(c(1,0,0),50),
> x1=rnorm(150,5,1), x2=rnorm
Dear all,
I used "sem" function from the package SEM to fit a model. However, I cannot
say if the model is correspondent to the data or not (chisquare test).
I used the commands:
model1 <- specifyModel()
estadio -> compflora, a1, NA
estadio -> compfauna, a2, NA
estadio -> interacoesobs, a3, NA

I have two or more data sets that have time stamps that vary from 5 mins to
3-5 hours.

You can also use clip() before abline():

But the clipping region will affect anything else you add to the plot after the
clip command. In package plotrix, ablineclip() sets and resets the clipp
Hi,
... so something like this? [in foo.R]
old.coll <- Sys.getlocale("LC_COLLATE")
Sys.setlocale("LC_COLLATE", locale="C")
Sys.setlocale("LC_COLLATE", locale=old.coll)
Cheers,

Hi.
For a spatial analysis (its visualization) I need to produce a map of
conditions and traits.
When I used SpatialPixelsDataFrame (sp package) my grid cells were regular
and between each row was a small gap, which is not only messy but incorrect.
So I generated the coords of each grid from the

package is great, but has the limitation that it is only able to read

there's a nice unix/linux/... library known as imlib2 that is able to
read and write image data in many different formats.

Very great help.
Bunch of thanks.

Relatively new user with a question regarding abline.
I want to draw a st. line fit to some data but I want the line to span the

In short the line spans xmin to xmax(of plot axis) but I want it to span

Dear David and Dan,
Yes, the column labelled "bootMed" is the median of the bootstrapped values. As
it turns out, this isn't documented in the help for the car package, nor in the
on-line appendix on bootstrapping from the CAR book. It's easy, however, to
print car:::summary.boot to see the str

Dear Amir,
There are a couple of panel functions in loa, a package of lattice add-ins,
that might be of help:

# Use a subsample of lat.lon.meuse dataset in loa
temp <- lat.lon.meuse[sample(1:155, 15),]
# plot Cu/Pb/Zn pie plots at sampling locations
loaPlot(copper+lead+zinc~longit
