beta binomial distribution installation
Hi,
I did a quick search for other packages that provide the beta binomial
distribution and found "rmutil".
> install.packages("rmutil")
The package has the CDF (pbetabinom) and inverse CDF (qbetabinom) among
other functions.
HTH,
Eric

beta binomial distribution installation
Hello,
Thank you for your response. I need to install RankTail package since it contains the beta binomial distribution, CDF and inverse CDF in the usual form which I need to use. However rmutil package contain unusual forms for these functions. So it is easier for me to deal with the forms are contained in RankTail.
I tried to install bioconductor package, using the following commands but I

Hello,
I tried to install package ?TailRank? using the command install.packages (RankTail) and library (TailRank) but I got the following errors. So, how can I install TaiRank in Rstudio to have se beta-binomial distribution, CDF and inverse CDG of beta-binomal?
The commands I used are:

Hi there,
It looks like you also need the bioconductor package biobase, I found instructions for downloading that package here: www.bioconductor.org/install
Good luck.
Cheers,

Power calculation using pwr.t.test()
Dear R experts,
I have conducted a power calculation in order to estimate the number of
subjects needed to detect an effect size of d=0.28 (cohen's d) for a
difference between two independent groups (alpha level should be 0.05 and
the effect should be detected with 80% probability).
The results from the code below indicates that I would need n=400 subjects
(200 in each group). This is seems

Trouble installing pwr package
Hi all,
I'm having trouble getting access to the pwr. This is on Ubuntu Lucid Lynx,
64 bit.
I'm installing pwr via packages.install('pwr'), and loading it via
library(pwr), both of which appear successful.
Strangely, I never get access to the pwr object in R.
I tried installing it to /usr/local/lib/R/site-library and
~/R/x86_64-pc-linux-gnu-library.

problem subsetting data frame with variable instead of constant
Hello,
I've encountered a very weird issue with the method subset(), or maybe this
is something I don't know about said method that when you're subsetting
based on the columns of a data frame you can only use constants (0.1, 2.3,
2.2) instead of variables?
Here's a look at my data frame called 'ea.cad.pwr':

Member Server in Active Directory
I'm trying to join a Samba 3.0.4 (compiled from source on Debian) to an

properly check for _DSM function support and Optimus support for vga_switcheroo
Hello guys,
I've prepared a patch based on my findings for the bbswitch module
(https://github.com/Lekensteyn/acpi-stuff/tree/master/bbswitch). This adds
a proper
check whether a _DSM function is supported or not and make OFF / ON for
vga_switcheroo work for nVidia Optimus models. The patch is based against
the
mainline kernel.
It has been tested on my Clevo B7130 laptop running kernel 3.2

power.t.test (PR#13891)
Full_Name: Michael J. Lew
Version: R version 2.9.1 (2009-06-26)
OS: OS X
Submission from: (NULL) (210.49.195.149)
The default function power.t.test gives inaccurate values, particularly with
large sig.level.
There are two reasons for me to propose that power.t.test is inaccurate:
1. When sig.level approaches 1, so should the power. However,

pwr.prop.test and continuity correction
Hi,
I am trying to sort out a discrepancy between power calculations results
between me and another statistician. I use R but I am not sure what she
uses. It is on the proportions test and so I have been using
pwr.prop.test. I think I have tracked the problem down to pwr.prop.test
not using the continuity correction for the test (I did this by using

SSweibull() : problems with step factor and singular gradient
Hello
I am working with growth data of ~4000 tree seedlings and trying to fit non-linear Weibull growth curves through the data of each plant. Since they differ a lot in their shape, initial parameters cannot be set for all plants. That’s why I use the self-starting function SSweibull().
However, I often got two error messages:

[PATCH V2 1/4] clk: allow non-blocking for nouveau_clock_astate()
There might be some callers of nouveau_clock_astate(), and they are from
inetrrupt context. So we must ensure that this function can be atomic in
that condition. This patch adds one parameter which is subsequently passed
to nouveau_pstate_calc(). Therefore we can choose whether we want to wait
for the pstate work's completion or not.

pwr/macros: Stop playing Russian roulette on data memory
This patch fixes the pwr firmware to play nicely at least on NVA3. Because Martin might send more patches soon, I didn't include a regenerated nvXX.fuc.h. To me it makes more sense if all patches are merged then, and a final patch regenerates the headers in one go. Of course, I did test this patch and found it to work as intended, so feel free to pick up as you please.
