We are using R to analyse microarrays datas by ANOVA.
We would like to set up Mixed Model analysis, using the "lme" function
within the nmle package.
However, we have problem in understanding and getting the right formula to
build a "groupedData" object which appear to be required for lme to work.
I ve read all the available nmle package s Users guides and manuals, but
explications are scarce.
Does anybody have an experience in using this function for microarrays datas
analysis and could send me informations or, if possible, a resolved exemple
(input table of datas, formula of the model, ouput...) ?
Maybe other R functions are usefull and easier to implement Mixed Models
ANOVA for microarrays analysis, any suggestions ?
I thank you in advance for your reply.
