R-help question
Hi there,
I have subscribed to R-help but am not sure how to view or post questions? I think this is the right way.
I am planning on doing a multivariate regression investigating the relationship between depression (a continuous variable) and social support variables (mostly continuous, some categorical) among older people. I have a number of demographic and health-related variables that I am

Wilcoxon Rank-Sum Test with Bonferroni's correction
Dear all,
I am trying to run Wilcoxon Rank-Sum Test with Bonferroni's
correction. I have two lists: l0, l1:
mapply(function(x,y)wilcox.test(x,y)$p.value, l0, l1)
How do I run Bonferroni's correction on mapply? Any help is much apperciated.
Thanks,

wilcoxon test with bonferroni correction
Hi!
I need to run a wilcoxon (Mann-whitly, in fact) test with bonferroni
correction, as I am running 10 consecutive wilcoxon test not
independent, and I know that bonferroni will partially correct for
this problem, but I have no idea how to do it with R, I have been
looking in the archive but couldn't understand how to do it.
The format I am using at the moment is

Bonferroni simultaneous confidence intervals for multiple regression
Hi,
I'm having no luck figuring out how to find Bonferroni simultaneous confidence intervals to obtain a family of estimates in R. Does anyone know how to do this?
Thank you!

bonferroni en R
Hola a todos/as
estoy analizando un diseño factorial con una variable intrasujeto y una inter-sujeto. Ambas resultan significativas en el anova y quiero hacer un análisis por pares, pero aún no sé como puedo hacerlo en R. Me interesan ambos Bonferroni y Tukey. ¿Alguien podría indicarme?
Gracias

calculating p-values from t-values for a Bonferroni adjustment
I am performing a sequential bonferroni adjustment on the results of an
ANCOVA but the equation I have for calculating p-values from the t-values is
not working. I can't seem to find it anywhere else. This is the code I have
now: 2*(1-pt(t,df)) where t=t-value and df=degrees of freedom from the
ANCOVA. Is there an error in the code? maybe another way to find the
p-values? Help!

Bonferroni with unequal sample sizes
Hello-
I have run an ANOVA on 4 treatments with unequal sample sizes (n=9,7,10 and 10). I want to determine where my sig. differences are between treatments using a Bonferroni test, and have run the code:
pairwise.t.test(Wk16, Treatment, p.adf="bonf")
I receive an error message stating that my arguments are of unequal length:
Error in tapply(x, g, mean, na.rm = TRUE) :

Partek has Dunn-Sidak Multiple Test Correction. Is this the same/similar to any of R's p.adjust.methods?
The Partek package (www.partek.com) allows only two selections for Multiple
Test Correction: Bonferroni and Dunn-Sidak. Can anyone suggest why Partek
implemented Dunn-Sidak and not the other methods that R has? Is there any
particular advantage to the Dunn-Sidak method?
R knows about these methods (in R 2.1.1):

How to set the number of multiple comparisons (Bonferroni-Holm)
Hello.
We have a question concerning the nonparametric analysis of a dataset, which
resulted in rejection of the null hypothesis (Kruskal-Wallis-test = H-test).
In order to find out which sample means actually are statistically
different, we want to do multiple comparisons with the Wilcoxon rank sum
test (= U-test); the p-level should be corrected according to
Bonferroni-Holm. Thus we decided to

Can R do rts (Regular Time Series) like S-Plus?
Dear readers,
S-Plus have a rts function (Regular Time Series), which is used like so:
fveks<-read.csv('http://louise.hoffman.googlepages.com/veks.csv',header=TRUE,sep=',')
attach(fveks)
acf(ts.intersect(rts(HC.f),rts(Ta.f),rts(GR.f),rts(W.f)))
Warning the csv file is 750kB.
Can the same be done in R?
Lots of love =)

inconsistency between gamma and choose functions
Please can someone explain why I seem to get these contradictory results?
choose(5,2)
[1] 10
gamma(6)/(gamma(3)*gamma(4))
[1] 10
gamma(6)/(gamma(3)*gamma(4)) == choose(5,2)
[1] TRUE
# all's well so far.
# now look what happens:
gamma(21)/(gamma(6)*gamma(16)) == choose(20,5)

# check individual terms:
gamma(21)/(gamma(6)*gamma(16))

Letter-based representation of pairwise comparisons
Hi!
I have been working several years with R but it's my first public question.
I hope I'll be clear :) .
This question is related to obtaining letter-based representation of
non-parametric pairwise comparisons.
I have a dataframe with this structure (but with quite more rows and cols):
A B C factor
1 2 2 one
2 1 2 one
2 2 3 two
2 3 2 two
1 4 2 three
9 8 1 three

ks.test not working?
Hi,
I am performing GEV analysis on temperature/precipitation data and want to use the ks.boot function but I am unsure of how to implement it using the pgev distribution.
For example:
ks.test(data,pgev,shape,location,scale)
ks.boot(data,(distribution parameters?),alternative="pgev",nboots=1000)
Any advice? Apologies in advance if I have used the wrong email address.

[LLVMdev] Removing old JIT CodeEmitters for ARM and PPC
Sorry for speaking too soon. It is missing from 3.2 which is the version I have been using. If it is already implemented than it is very good news.
Thanks.

books on Time series
Dear list fellows,
I want to study time series and use R to analyse time series of fishing
data from several species (landings and cpue) investigating the
correlation between them and with environmental factors (water
temperature, wind, etc.).
Searching at Amazon I found three books with examples in R:

psychometric functions
Hi,
I want to fit some psychophysical data with cumulative gaussians. There is
quite a convenient toolbox for matlab called 'psignifit' (formerly known as
'psychofit'). It allows the lower bound of the sigmoid to vary slightly from
zero, aswell as the upper bound to vary from one. with these two free
parameters, the fitted function is less sensitive to noisy data and
outliers.
