Hello, I am a relatively new R-user who has a lot to learn. I have a large dataset that is in the following dataframe format:
red A B C green D blue E F Where red, green and blue are "species" names and A, B and C are observations (corresponding to DNA sequences). Each observation can only belong to one species. I would like to list the observations in one column, with the species they belong to in the next. Like this: A red B red C red D green E blue F blue I have tried using reshape() and stack() but I cannot get my head around it. Any help is highly appreciated!
