Re: [R] automating aov function

[Michael Morley]

If you want a matrix (perhaps a data.frame so you can add different data 
types(gene name, accession, etc) of just the F and Ps from each anova.
Something like this works for me. Though I'm a newbie too, so if there 
is a better way someone let me know!
--
#create 2 by # genes matrix, can add row names or col names
#precomputing your matrix will save some computational time as compare 
to rbind
#assume genes is some matrix or data.frame

results <- matrix(ncol=2, nrow=length(genes[,1]))
for(i in 1:length(genes[,1]){
an <- anova(lm(formula,data))
results[i,] <- c(an$F[1], an$P[1] )
}

Don't forget about the multiple testing!

I am running the aov function to determine the linear relationship between
individual genes and a number of covariates in a micro-array data set.  My
aov function is working, but I have not been able to write a code to save
these results in a matrix.  I am using the following code or a slight
variation of this code:

for(i in 1(length(m[1,])-20)

{tmp<- aov(m[,i]~treat, data=m)

{results [i] <- tmp}}

Any help would be appreciated.


Thanks,

Nina

Re: [R] Opening help pages in new tab of existing Mozilla Firebird

[Michael Morley]

Try this Mozilla Firefox extension,
http://www.intraplanar.net/projects/tabprefs/
If you more control over tabs there is this extension as well

Sorry if this is obvious, but I can't find anything.
