Dear all,
This is something for the combinatorics freaks amongst you (which I am
certainly not :-).
I do the following problem to solve and was wondering if this can be easily
done using R:
I have a set of, let's say, 10 variables: n(varibale) = 10
e.g. var <- c(a,b,c,d,e,f,g,h,i,j)
per experiment, I want to pick 4 variables
e.g. exp1 <- c(a,b,c,d), exp2 <- c(e,f,g,h), ...
each variable should be present in 4 different experiments
each varibale may co-occur in max. 2 experiments with another variable
Questions:
1) What is the number of minimal experiments that all of the above
prerequisites are met?
2) Report a list of the combinations
It would be great to have a script that is flexible for all prerequisites.
Thanks a lot already in advance!
Nina
