It does. See `lower' and `upper' arguments.
Why are y and z not known? Say, you want the marginal of x, i.e. integrate
over x. Now, y and z are fixed. You fix them at different values, but they
are known.

Duncan,
That would appear to be exactly what I was looking for! I will follow
up if I have trouble after implementing the script this'll be used in. I
suppose I'd be wondering whether R is a reasonably fast language to use for
this type of task (given the very large long string size, and the

A simple maths question that I am trying to resolve with R: I need to
calculate the SE from a pvalue and it's beta... How to do this...?

Try
simtest - transform(simtest,

Hi Josh,
This is by no means the fanciest solution ever, but as there are
predict methods for many types of models in R, I thought I would show
it this way.
## fit the model
model - lm(probability ~ poly(temperature, 2), data = x)
## create line values
dat - data.frame(temperature =
Dear luri,
The metaSEM package
(http://courses.nus.edu.sg/course/psycwlm/Internet/metaSEM/) may be
used to fit structural equation models on the pooled
correlation/covariance matrices with weighted least squares as the
estimation method. You may refer to the examples in tssem1() and
tssem2().

Hi Geoffrey,
Here is one option (data named dfrm instead of data because data() is
a function too):

dfrm - data.frame(

year = c(2004,2005,2006,2004,2005,2006,2004,2005,2006),

You could try,

ddply(data, .(name), summarize, mean=mean(sale))
