Dear list,
I use SciViews R Console 0.8.9 with R-2.2.1 under Windows XP SP2, and
it works very well for most of time. However, sometimes, when
commands were executed by clicking F5, the error "Run-time error 521,

I installed odesolve package (0.5-15) in R 2.3.1 in a Solaris server

Dear list,
In some places (for example,
http://en.wikipedia.org/wiki/Support_vector_machine) , the polynomail
kernel in SVM is written as (u'*v + 1)^d, while in the document of
svm() in e1071 package, the polynomial kernel is written as
(gamma*u'*v + coef0)^d. I am a little confused here:

Dear list,
Given a vector of logical values, say
>a <- c(TRUE,TRUE,TRUE,FALSE,FALSE,FALSE,FALSE,TRUE,TRUE,TRUE)
Are there any R functions that can tell whether there are two or more
"TRUE" in a row in this vector?
Thanks,

Dear list,
This question is about Hidden Markov Model. Given a transition
matrix, an emission matrix and a sequence of observed symbols
(actually, nucleotide sequences, A, T, C and G), I hope to predict the
sequence of state by Viterbi algorithm. I searched R repository for
related packages. ms
Try trim() in gdata package.

Dear list,
I used read.xls in gdata package to read a worksheet in which certain
field contains very long character strings (nucleotides sequence,
nchar > 10,000). Then, the values in these fields are automatically
converted to "TOO LONG TO DISPLAY". How can I get those original

Dear list,
Are there any functions for calculating gamma (and its standard
error), which measures the association of ordinal factors in I x J
contingency table. I did a RSiteSearch but did not find any clues...

Hi Haibo,
Are there any character "#" in the cells? By default, the things at
the right side of the character "#" will be masked as comments.

Hi,
I have a question about interpret the results from logistic regression
model. I used a dataset from the book Categorical Data Analysis (2nd
Edition) by Alan Agresti.

Hi Veronika,
StepAIC does not do any test. But you may do a likelihood ratio test
on the difference between deviance of two models to judge which model
to use, simply like this,
> 1 - pchisq(deviance.i - deviance.j, df.i - df.j)
And then check whether the returned p value is small enough...

Hi Koskinen
For response variables with multiple categories, you may try polr() in
MASS package, which implement a proportional odds model. And you may
search the R archives, several threads discussed this problem
before...

Hi Stephen,
I think the tutorial written by Brett Presnell
(http://web.stat.ufl.edu/~presnell/Teaching/sta4504-2000sp/R/) is a
good start point for categorical data analysis using R.

You may fit the model using lm() directly - R will set up a coding for
qualitative predictor automatically (taking experiments as qualitative
predictor).
