Dear R users, I'm wondering how I can generate an arbitrary number of loops in R. For instance, I can generate two "for" loops to get ICC among any two-way combination among 10 variables. Here is the code
n<-10 for (i in 1:(n-1)) { for (j in (i+1):n) { icc(cbind(DATA[,i],DATA[,j])) } } If I need three-way combination, then a code with three "for" loops will be: n<-10 for (i in 1:(n-2)) { for (j in (i+1):(n-1)) { for (k in (j+1):n) { icc(cbind(DATA[,i],DATA[,j],DATA[,k])) } } } But how can I write a code if I need all m=2, 3, 4,... loops for arbitrary m-way combinations? Thanks! Daisy ________________________________ Electronic mail from Children's Mercy Hospitals and Clinics. This communication is intended only for the use of the addressee.
