Histogram Principal component analysis in R
Hi,
I am trying to do a Principal component analysis on histogram data.
Basically, I have a group of subjects and for each of them, I have a column
of bin-counts (vis-a-vis intervals) and a corresponding column of
frequencies (or normalized frequencies). The bin counts are the same for all
the subjects. I also have a group-averaged histogram (with the same bin
counts and a column of frequencies)

Testing whether a number belong to a set
Hello everyone,
I am stuck with an apparently simple issue :
i) I have two sets S1 and S2, each containing a large number of integers,
say zip codes.
ii) Now, I just want to test whether a particular zip code belong to S1 or
S2 or neither of them.
iii) If it belongs to S1, the area/region gets a particular label, say 1; if
it belongs to S2, it gets a label 2 and if it doesnot belong to either S1

Fitting mixed effects Baseline category logit models
Hello everyone,
I want to fit a baseline category logit model (with 3-4 categories) with
nested random effects.
(For example, I have clusters(i) and households within clusters (j)
resulting in the nested
random effects structure : b_i +d_j(i)). Is there a R function/package that
I can use ? Any help
will be much appreciated.
Thanks and regards,

Bivariate normal regression in R
Hello everyone,
I need to fit a bivariate normal regression model to a dataset where the
same covariate (say, X) influences two separate but correlated responses
(say, Y1 and Y2). So, the bivariate
model would look like :
Y1 = a1 + b1*X + e1
Y2 = a2 + b2*X + e2
where e1 and e2 are error terms which can be correlated. Is there any
package in R which can help me fit this model ? Any help will be

Fwd: makeconf issue on R-devel 2006-03-12 r37524
I sent the message below to r-sig-mac yesterday, but having no reply
I decided to explore a bit myself and found that editing:

restored the functionality of R CMD INSTALL.
Is this a known issue?

Suggestions to speed up median() and has.na()
Hi,
I've got two suggestions how to speed up median() about 50%. For all
iterative methods calling median() in the loops this has a major
impact. The second suggestion will apply to other methods too.
This is what the functions look like today:
> median
function (x, na.rm = FALSE)
{
if (is.factor(x) || mode(x) != "numeric")
stop("need numeric data")

MKL Acceleration encouraging; need adjust package builds?
Dear R-devel:
The Cluster administrators at KU got enthusiastic about testing
R-3.2.2 with Intel MKL when I asked for some BLAS integration. Below
I forward a performance report, which is encouraging, and thought you
would like to know the numbers. Appears to my untrained eye there are
some extraordinary speedups on Cholesky decomposition, determinants,
and matrix inversion.

MKL Acceleration encouraging; need adjust package builds?
Hi Paul,
We've been through this process ourselves for the Revolution R Open project. There are a number of pitfalls to avoid, but you can take a look at how we achieved it in the build scripts at:

There are also some very useful notes in the R Installation guide:

any other fast method for median calculation
Hi there,
I got a data frame with more than 200k columns. How could I get median of each column fast? mapply is the fastest function I know for that, it's not yet satisfied though.
It seems function "median" in R calculates median by "sort" and "mean". I am wondering if there is another function with better algorithm.
Any hint?
