R help - Aug 2009 - write file to date-stamped folder

Hello,

I would like to be able to write all files produced on one day to an output
directory with that date stamp, or alternatively stamp the date in the
filename. So that if i run the same code the next day the files will not be
overwritten.

here's what i have to start with:
baseDir = getwd()
outputDir = paste(baseDir,"/OutputData-", Sys.Date(),sep="")

and lets say i want to write the table "test.table" to a file:

write.table(test.table, "test.table.txt", sep="\t")

How do i make this write to outputDir?

Thanks.

Try this:

write.table(test.table, file.path(outputDir, "test.table.txt"),
sep="\t")

How about:
> test.table <- matrix ( rnorm ( 25 ) , ncol = 5 )
> outputDir = paste (
+   getwd ( )
+   , "/OutputData-"
+   , Sys.Date ( )
+   , sep = ""
+ )
> dir.create ( outputDir )
> write.table (
+   test.table
+   , paste (
+     outputDir
+     , "test.table.txt"
+     , sep = "/"
+   )
+   , sep = "\t"
+ )
