How small does a p-value need to be to warrant attention, however?
Witness Fisher’s comment that:
“. . . we may, if we prefer it, draw the line at one in fifty (the 2 per cent
point), or one in a hundred (the 1 per cent point). Personally, the writer
prefers to set a low standard of significance
Here are several ways to get there, but your original loop is fine once it is
corrected:
> for (i in 1:2) smean[i] <- mean(toy$diam[toy$group==i][1:nsel[i]])
> smean
[1] 0.271489 1.117015
Using sapply() to hide the loop:
> smean <- sapply(1:2, function(x) mean((toy$diam[toy$group==x])[1:nsel[x]
i want to select the significant genes form 5 clusters (groups) by one way
ANOVA in
r###
# i want use One way ANOVA to select the siginificant from the clusters above
selectgene <- function(GropuData,pvalue=0.0
This has nothing to do with R. Post on an ecology list or talk with
your teachers.
Cheers,

This is way OT for this list, and really has nothing to do with R.
Post on a statistical list like stats.stackexchange.com if you want to
repeat a discussion that has gone on for decades and has no
resolution.
You really should be spending time with the literature, though. Have
you? "Cross validat

Hi! I’m Zatul from Malaysia. I’m currently doing simple task on BACI approach
in ecology study. I’m a newbie in ecology study. Perhaps, I can get link and
some idea regarding how to analyse BACI data. Tq.

Hi, I'm trying to build R on windows and i'm getting the following error
when i run the "make all recommended" command:
C:/Rtools/mingw_64/bin/windres -F pe-x86-64 -i dllversion.rc -o
dllversion.o
comm: file 1 is not in sorted order

Throughout my R journey I have noticed the way we can use given data to
develop and validate a model.
Assume that you have given data for a problem
1. train.csv
2. test.csv
*Method A*
*Combine train+test data* and develop a model using the combined data. Then
use test.data to validate the model
Hi Axel,
Maybe the following works for you.
