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.

Subject: [R] Scripting issues



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
