Need help with function writing
Hello:
If anyone could guide me with this I would greatly appreciate it. Thanking you in advance for your assistance.
Using a 3-level input factor alternative so that a function(below) can compute both a two-sided and one-sided p-values. Making the two-sided test the default. And produce output information about which alternative was tested. Where would I place the ifelse statement?

glm syntax question
Hello,
I'm new to R and have a very basic syntax question for the
functionglm. I am using the function glm() to do a regression on a
data set. I want to run this function in a while loop, so I need to be
able to do two things:
(1) I need to be able to have my list of variables in the regression
be based from a variable vector instead of hard code.
(2) I need to be able to collect the

easy way to do a 2-D fit to an array of data?
Hi,
I've got a matrix, Z, of values representing (as it happens) optical
power at each pixel location. Since I know in advance I've got a
single, convex peak, I would like to do a 2D parabolic fit of the form
Z = poly((x+y),2) where x and y are the x,y coordinates of each pixel
(or equivalently, the row, column numbers).
Is there an R function that lets me easily implement that?

Multivariate regression
Hi,
Suppose I have a multivariate response Y (n x k) obtained at a set of
predictors X (n x p). I would like to perform a linear regression taking
into consideration the covariance structure of Y within each unit - this
would be represented by a specified matrix V (k x k), assumed to be the same
across units. How do I use "lm" to do this?
One approach that I was thinking of

Additional args to fun in integrate() not found?
Hello, fellow Rdicts,
I have the code for the program below. I need to integrate a function
of "x" and "p". I use integrate to integrate over "x" and pass "p" as
an additional argument. "p" is specified and given default value in
the argument list. Still, integrate() cannot read "p", unless I
explicitly insert a numeric value in the

help with ARIMA and predict
I'm trying to do the following out of sample
regression with autoregressive terms and additional x
variables:
y(t+1)=const+B(L)*y(t)+C(1)*x_1(t)...+C(K)*x_K(t)
where:
B(L) = lag polynom. for AR terms
C(1..K) = are the coeffs. on K exogenous variables
that have only 1 lag

Lattice 3d coordinate transformation
Hello List!
I asked this before (with no solution), but maybe this time... I'm
trying to project a surface to the XY under a 3d cloud using lattice.
I can project contour lines following the code for fig 13.7 in
Deepayan Sarkar's "Lattice, Multivariate Data Visualization with R",
but it fails when I try to "color them in" using panel.levelplot.

how to do interpolation
Hello R Users,
How to make a variable equidistance with time i.e. how to interpolate a
variable if it is not sampled at equal time interval.
Many thanks,

Plot problem !
Hello,
Is there a simple way to make a plot with xy coordinates and a z value
which determines the size and the color of point on the plot?
Thanks for your help !

Error message "cs_lu(A) failed: near-singular A (or out of memory)"
Hi there everyone,
I have the following model (this is naturally a simplified version just for
showing my problem, in case you're wondering this is a translog cost
function with the associated cost share equations):
C ~ á + â1 log X + â2 log Y + ã1 log Z + ã2 log XX
C1 ~ â1 + â2 log YY + ã1 log ZZ
Then I have some restrictions on the coefficients, namely that the sum of â
equal 1 and the

[RFC PATCH 10/11] PCI/MSI: Split the generic MSI code into new file
MSI interrupt will not only used in PCI device, more
and more Non-PCI device also want to use MSI. ARM
GIC v3 spec says in ARM platform with GIC v3 controller,
Non-PCI device can also be design to support MSI to
simplify interrupt wires, for the existing Non-PCI
device, consolidator is designed and used to translate
legacy interrupt to MSI. So for support Non-PCI MSI

HWEBayes, swapping the homozygotes genotype frequencies
I evaluated the Bayes factor in the k=2 allele case with a "triangular"
prior under the null as in the example in the help file:
HWETriangBF2(nvec=c(88,10,2))
[1] 0.4580336
When I swap the n11 entry and n22 entry of nvec, I received totally
different Bayes factor:
