Dear R users given a numeric array (a sequence of reals), I am interested in finding the subsets of sequences (each with start and end index) which match a given sd range. I read the docs on match and which and the "see also" but could not come up with a way. I could loop with a stepping window over the sequence but that would be limited to a fixed size window, I guess I as well

...2.2009 0.5502 so we get the 2.2009 on 4 df SS for redisuals with mean SS 0.5502. Then I would do: mNp<-mean(y[(vac=="N")&(inf=="+")]) mNm<-mean(y[(vac=="N")&(inf=="-")]) mYp<-mean(y[(vac=="Y")&(inf=="+")]) mYm<-mean(y[(vac=="Y")&(inf=="-")]) c( mYp, mYm, mNp, mNm ) ##[1] 2.4990492 0.5532018 2.5212655 -0.3058972 c( mYp-mYm, mNp-mNm ) ##[1] 1.945847 2.827163 after which: 1-pt(((mYp-mYm)/sqrt(0.5502)),4) ##[1] 0.02929801 1-p...

Hi So carrying on my use of analysis of variance to check for the effects of two factors. It's made simpler by the fact that both my factors have only two levels each, creating four unique groups. I have a highly significant interaction term. In the context of the experiment, this makes sense. I can visualise the data graphically, and sure enough I can see that both factors have different

Is there an element-by-element multiplication in R, like the .* operator in Matlab? eg: A (2x3) B (2x3) C=A.*B C (2x3) C = [[a11*b11 a12*b12 a13*b13]; [a21*b21 a22*b22 a23*b23]] I can't find one... Thanks -Mike Gates
