Hallo,
I am a new user of 'R'. I have been trying to download it onto my Mac (OSX
2.8). For some reason it seems to download ok and look ok but then it
doesn't actually open. Can somebody help me this?

Hi Gabor and Dimitris,
I was wondering if this question was frequent enough to be in the R
FAQ under R Miscellanea and thought of something like this
Q. How do I plot two curves on the same graph?
A. Plot the first curve using the plot() command and add lines using
lines(). For example

Dear Rense,
I already wrote a function, appended below, to compute effects for SEMs, as
a method for the effects() generic. I've been thinking about adding this to
the sem package, possibly with asymptotic standard errors computed by the
delta method, as suggested by Michael Sobel. If I do so, I c
Hi,
If I understand correctly the
Var(X \hat{\beta}) = X (X'X)^{-1}X' \sigma^2, where X will now be "x.pred".
Which should be easily obtained by performing the matrix computation and
multiplying it with the estimate of the variance.
For more details about different aspects of the estimate and v
Dear John,
thank you very much for your reply. The suggestions you make for
calculating the direct and indirect effects are exactly what I was
looking for. Although I'm very new to SEM and not at all very
experienced in R, I tried to put them together in a function (called
decomp) and expa

Assuming newdata is the same for all the models and is included in a
data.frame called New:
list_glm <- paste("glm", 1:10, sep = "")
sapply(list_glm, function(x) predict(get(x), newdata = New))

Dear Listers,
If I have several glm objects with names glm1, glm2 and want to apply
new data to these objects. Instead of typing "predict(glm1, newdata)..." 100
times, is there way I could do so in a loop?
Thank you so much!

Hi Rense,
Not sure how robust this is, but maybe to get you started:
In R console:

Copy that line to or part of it to the clipboard.

\"R.app\" to cmd y'")
If course you could use this in an R function. I woul

A complete explanation of the issues that you raise is awkward in an email,
so I'll address your questions briefly. Section 8.2 of my text, Applied
Regression Analysis, Linear Models, and Related Methods (Sage, 1997) has a
detailed discussion.

I think this starts from the position of a batch-oriented package.
In R you can refit models with update(), add1() and drop1(), and
experienced S/R users almost never use ANOVA tables for unbalanced
designs. Rather than fit a pre-specified set of sub-models, why not fit
those sub-models that ap

Oops, forgot to include the Subject. sorry for that
sloppiness.
Yes, you can, as documented in ?connections, but
on the Mac you would have to use:
read.delim(pipe("pbpaste"))
You can also use pbcopy to copy to the clipboard.
