Users, I am currently running scripts on a rather large dataset. Many times I sort the data into smaller datasets and must analyze them individually. My instincts are to make a for loop, but I can't seem to find a way to index each sub-dataset (data frames as the case would have it). I would make an array, however, the data types of the columns are different and as I understand, an array cannot handle this type of structure. Any advice on how to do this? Any help is greatly appreciated. Thank you, Dave Mitchell [[alternative HTML version deleted]]
Could you explain a little more about exactly what you are trying to do, or provide some sample code. How are you creating the subsets? Can you put them in a list and then process them from the list, or you could use an 'lapply'. So some details would be helpful.

How about making a list of data frames, then you can use either a loop
(mylist[[i]]) or often simpler to use the lapply and sapply functions.

Users,
I am currently running scripts on a rather large dataset. Many times I sort
the data into smaller datasets and must analyze them individually. My
instincts are to make a for loop, but I can't seem to find a way to index
each sub-dataset (data frames as the case would have it). I would make an
array, however, the data types of the columns are different and as I
understand, an array cannot handle this type of structure.
Any advice on how to do this? Any help is greatly appreciated.
Thank you,
Dave Mitchell
