Hello R experts,
I wonder if there is any package to estimate this kind of models in R:
Multi-state Multi-spell Survival Models with Heterogeneity
One of the most powerful programs for survival models is CTM, the
Continuous Time Model, developed for NIH at NORC under the direction
of James J.
Hi,
I find it cumbersomesome the I have to use \%*\% in .Rd files vs. %*% in
.R files. R CMD check will refuse %*% in .Rd files. I would like to have
%*% in .Rd files to be able to execute expressions with matrix
multiplication from .Rd files directly, but ESS (version 5.13) would
refuse to
I am a very new R user. I am trying to write functons and debug functions.
One problem for me is that I need to alwasy copy the whole function body and
resubmit to R console every time I changed even one line of the function.
Because I have long algorithm function, copying and pasting is very
Dear all,
I am trying to plot KM curves with confidence bands with function survplot
under package rms.
However, the following codes do not seem to work. The KM curves are produced,
but the confidence bands are not there.
Any insights? Thanks in advance.

Hi All. Sorry to bother you. I have a question about fisher exact test.
I counted the presence of gene mutation in two groups of samples. My data is as

Hi, I am a novice in R. It will be greatly appreciated if someone
can advise me with the following questions.
1) How to highlight reference range in forest plot? For example, if 1.5-2
is the reference range, I would like to have all the area between 1.5-2 to
be highlighted (such as in grey
Dear UseRs,
I'm running a chi-squared test where the expected matrix is the same as the
observed, after rounding. R reports a X-squared of zero with a p value of
one. I can justify this because any other result will deviate at least as
much from the expected because what we observe is the
Hello R experts,
I have having a difficult time figuring out how to perform and interpret an
ANCOVA of my nested experimental data and would love any suggestions that you
might have.
Here is the deal:
1) I have twelve tanks of fish (1-12), each with a bunch of fish in them
2) I have three

Read about Yate's continuity correction - your formula does not use it
and chisq.test does unless you suppress it:

Dear All:
I plotted a histogram with Abline, clipping with color codes but i run into
some problems. The abline' does not show up at all, and when i request
the 'prob=True' (to obtain the freqs), my clipped region colors the section
of the graph instead of the plot only.
Is there any way i
