First of all, thanks for all the replies!! What you have written helps, but is not entirely the answer to my problem. What I'd have is the creation of new data.frames each of one named with the ID of the original dataframe and with all the columns.
No you don't! You want what you were provided, a list of data frames. Anything you want to do can be done, probably more conveniently, with that. Read "An Introduction to R" and learn to work with lists. Being a newbie is no excuse for not making an effort to learn. -- Bert
For example, in the original dataframe one column (ID) has 5 different elements: ID value1 value2 x1 10 12 x1 12 22 x1 11 9 x2 15 10 x3 11 11 x3 13 8 I need a command ables to split the dataframe in other smallest and separated dataframes, so that they look like x1 is ID value1 value2 x1 10 12 x1 12 22 x1 11 9 x2 is ID value1 value2 x2 15 10 and x3 is ID value1 value2 x1 10 12 x3 11 11 x3 13 8 Sorry if I'm not able to explain it better and as I said I'm very new to R..... Thanks Matteo
