[R] What is the correct way of using function C() for factors:
The funciton c() works differently for strings and for factors: For strings:> l = c('a', 'b') > l[1] "a" "b" For factors:> l = c(factor('a'), factor('b')) > l[1] 1 1 What should be the right technique for merging factors? -- Svetlana Eden Biostatistician II School of Medicine Department of Biostatistics Vanderbilt University
