[R] How to save the output of "split" command as series of .csv files

[menno]

Hello,

I am looking for a way to quickly split a data frame containing daily
temperature readings into a series of individual data frames, one for each
year, in order to save them as individual .csv files which will be named
according to Year. I would prefer not to use a series of "subset" commands
given that there are a differing number of years for the various location. 

The data looks like this: 

   Day Month   Community     Year     MaxTemp MinTemp
   	1     1  	      '241552' 	        	1990      44        	 29
   	2     1  	      '241552' 		        1990      39         	 20
   	3     1        	'241552' 		        1990      35     	      24
	.	.	.			.		.	.	
	.	.	.			.		.	.
   	4     1  	     '241552' 	         	1991      23         	 23
   	5     1  	     '241552' 		        1991      33     	         31
   	6     1  	     '241552' 		        1991      45          	 44
	.	.	.			.		.	.	
	.	.	.			.		.	.


The "split" command   (data2<-split(data, data$Year)) essentially does what
I want, but I am unable to take the output from this command and save the
data from individual years in separate files. I would ideally like to have a
series of output files named "241552_1990", "241552_1991", etc. These data
files will then be run through a loop that I have already created. I have
attempted to feed the output of the split command directly into my
pre-existing loop, but doing so will require major re-writes to my script
due to column/row naming issues. 


Any information anyone could provide would be greatly appreciated. 

Thanks for your time,

David Roth
