...The purpose of my analysis is to compare the pattern of the whole genome 'gene expression' between the two tissue types. I have 'age' and 'sex' as covariates. Since 'age' and 'sex' definitely have influence on gene expression, I need to first filter out the proporation of 'gene expression' attributable to 'age' and 'sex', then compare the 'remaining gene expression' value between 'liver' and 'brain'. How to do the covariate adjustment to remove the effects of these two covariates? Should I do a 'step-wise' r...

Hi, I have a large matrix (SNPs) that I want to cycle over with logistic regression with interaction terms. I have made a loop but I am struggling to identify to the formula the name of the column in a way which is meaningful to the formula. It errors becasue it is not evaluated proporly. (below is a pilot with only 7 to 33 columns, my actual has 200,000 columns) My attempts: for (i in 7:33)

Hi, I try to make a selective plot, but it make an error. The subset only work with length < 4, it is correct? > plot((ocorrencia/isca)~frag,subset=especieama==c("grupo1","grupo2","grupo3","AnoplotermesSp1","NeocapritermesOpacus"),pch=c(1,2,3,4,5),xlab="?rea (ha)",ylab="Propor??o de iscas ocupadas por t?rmitas")

I am having an issue with Builder.node where it does not produce an error in firefox 1.5 however it just hangs and stops executing. For example if i run the following code, alert start pops up however Builder.node never pops up. alert(''start''); alert(Builder.node(''b'', ''test'')); Anyone have any ideas

Hi, First ,please excuse my poor English. Can someone help me on reading fortran binary object under R? I was trying to read mm5 data under R. However, I seem to stuck at reading fortran binary file storing met. data array. At the beginning, I used readBin() to read mm5 output directly with the following command. #mmout is a mmout file generated with mm5

Dear All, I'd like to fit a "kind" of logistic model to small data-set using nonlinear least-squares regression. A transcript of R-script are reproduced below. Estimated B and T (the model's coeff, herein B=-8,50 and T=5,46) seem appropriate (at least visually) but are quite diff from those obtained w/ SPSS (Levenberg-Marquardt): B=-19,56 and T=2,37. Am I doing something wrong in

..., however, is that someone needs to rewrite bitmap.c/bitmap.h, obstack.c and obstack.h, into C++. They are currently just modified versions of what gcc is using. You can get rid of the obstacks, of course. Using set<u32> or BitVector or something like it will result in a slowdown of mammoth proporations, and about a 10x memory increase. Trust me here, you don't want to use a non-sparse bitmap. BDD's are acceptable, but are about a 2x slowdown. With various optimizations that are going to be published in the next few months, you can get bitmaps to use just as little memory as BDDs would,...
