predict.zeroinfl not found
Hi Just a quick problem that I hope is simple to resolve. I'm doing some work with zero inflated poisson models using the pscl package. I can build models using zeroinfl and get outputs fom them with no problem, but when I try to use the predict.zeroinfl function, I get Error: could not find function "predict.zeroinfl".
I was using an older version of R, but still had the same

Removing default loess line from scatterplot ({car})
scatterplot() is autogenerating a regression and loess line. I want to remove
the loess line, but can only find samples for how to add it. I definitely do
not have code that adds it (see below), so I am puzzling...

Welch Two Sample T-Test
I know when I enter this into R:
> x = c(15, 10, 13, 7, 9, 8, 21, 9, 14, 8)
> y = c(15, 14, 12, 8, 14, 7, 16, 10, 15, 12)
> t.test(x,y,alt="less",var.equal=TRUE)
it shows:
Two Sample t-test
data: x and y
t = -0.5331, df = 18, p-value = 0.3002
alternative hypothesis: true difference in means is less than 0

Can't format x axis on a stacked plot of a zoo object
As an example data set:
set.seed(1)
z.Date <- as.Date(paste(2003, 02, c(1, 3, 7, 9, 14), sep = "-"))
z <- zoo(cbind(left = rnorm(5), right = rnorm(5, sd = 0.2)), z.Date)
tt<-time(z)
fmt<-"%b-%d"
labs<-format(tt,fmt)
plot(z[,1], xlab = "Time", ylab = "")
If I plot the data and don't like the format of the x axis I can do this:

A panel of contour plots through a iteration process
Dear all,
as you can see from the code I want to create *a panel of 11 contour
plots through
a iteration process*. I found a thread that address the issue of plotting
many contour.plots in the same device, but it does not address my problem!
I emphasize that the 11 contour plots must be appeared in the same device
through an iteration process and NOT individually!

Simple Likert count data visualization
Hello,
Before I start to construct something inferior myself I would like to know if such a plot function is already out there.
I have count data of a small survey with a few questions which use a scale from "Strongly disagree" to "Strongly agree" and similar things. What I would like to have for a slide is a plot which shows for each question a line over this scale and the

cluster analysis in R
I have two issues.
1-I am trying to use morphology to identify gender. I have 9 variables, both
continuous and categorical. I was using two-step cluster analysis in SPSS
because two-step could deal with different types of variables. But the
output tells me that an animal is in cluster 1 or 2, it does not give me a
probability (ex. 0.70 cluster 2). I also did not want to specify that I
want two
