listing all occurrences in a vector
...data.frame(c(2,3,2,5),c(1,2,3,1)) > colnames(a)=c("DEPTH","NUMBER") I want a column or a vector where all the DEPTHs are listed: 2, 3, 3, 2, 2, 2, 5 (NUMBER=1 in all cases). Is there any simple solution to the problem? Thanks, Jonas Jonas Fransson Ph.D.stud. ?
