R help - Jan 2013 - error using the subset function in a for loop index

Hi all, I have attached the function file (revisedfunction) and the list
of station IDs (StationIDs) in .pdf format documents.

I have written a function to perform various operations on the station
IDs in two groups. The first 6 station IDs require one less step than
the remaining 68 station IDs. The file referenced at the beginning of
the function is the file containing the StationIDs.

I created a for loop to allow indexing through each set of station IDs.
I have not been able to run the complete function because I can not
subset the for loop index within the subset function.

Is there a way to perform this operation: Sample <-
subset(Sample,station_id==[i]) within the indexed for loop using another
built-in function or through the subset function? The attached file
revisedfunction provides the full function code in which that line
creating another instance of the variable Sample is excerpted from.

Thank-you.
