I need to group some subjects according to two variables (var1, var2) I have a data frame that looks something like this: Subject var1 var2 1 400 150 2 320 100 3 580 600 4 145 789 Each suject would fall into one of 2 categories ('A' or 'B'). I want to find (and see) all the possible combinations of letter assignment that exist, but every combination needs to have an equal amount of subjects categorized as 'A' or 'B'(eg. if I have 20 subjects there should...

...60 0 1 4 50 1 1 5 90 0 1 . . . . . . . . . . . . 100 50 1 0 -------------------------------- In the dataset, 'subject' is suject ID, 'surv' is the survival time, 'censht' is the indicator of censor, 'educ' is the strata variable indicating the education status. How convert such SAS codes to R code? thank you very much, karena -- View this message in context: http://r.789695.n4.nabble.com/Convert...

...bject (id) was 5 year old,... "VEMS18A" is the value when the subject(id) was 18 year old I want to make a new data wich colnames will be : "id","age", and "VEMS" Where "age" will be the age when the value in "VEMS" was measured for the suject "id"... So I need to copy all the values of the columns "VEMS5A",... "VEMS18A" in "VEMS" and in "id" the "id" corresponding and in "age" the values between 5 and 18 corresponding to the age of the subject when the mesure was don...

...oups of subjects of unequal sample size (G1 (n=7), G2 (n=7), G3 (n=4)). for Each subject I have 4 measures corresponding to the crossing of 2 factor (A & B) of two levels each. my dependant variable is X. After reading a lot of tutorials on R I have tried the summary(aov(X~GROUP*A*B+Error(SUJECT/(A*B) ) This results are with "type I SS". What's wrong with these results ? Should I use type III SS and, if so how to enter my design in Anova (car package, I still have not the J. Fox's book) ? I have clearly not understood the difference between type I & III (with th...

Ooops, I guess a suject will get some of you to read this, hey? Hi All, Wondering if there is a document that tells how to get wine printing through a cups printer working? Yes I know the wine docs say it's all magic and if you're using cups your printing will magically work, but for some reason, it doesn'...

Actually, this is such a trivial bug to fix, that for many it probably makes more sense to edit fs/fcntl.c and recompile rather than suject themselves to the latest pre-release kernel...unless they like testing pre-releases. Just out of curiosity...word of this broke in linux-kernel and bugtraq in the last days of June. Were the linux-security moderators away on holiday, or do they live in a time zone several days behind the rest of...
