R help - Jan 2006 - How do you convert this from S Plus to R - any help appreciated . thanks

exportData(MU.Cost,paste("C:/RAUDSL/S",as.character(MU.Cost$Run.Id[1]),"
.",as.character(MU.Cost$MU.Id[1]),".MU.PRICE.OUTPUT.txt",sep=""),append
= FALSE,type="ASCII",quote=FALSE)

There is an `R Data Import/Export' manual to guide you on how to do data 
export in R.  Please consult it.

I only know vaguely what format exportData(type="ASCII") uses, and it
is
probably easier to work out what you want and tailor write.table() to give 
that.  (I am not aware that the fine details of exportData are 
documented.)

  Looks like perfectly good R to me.

  Except there's no exportData function. I assume this is an Splus 
function that R doesn't have, in which case telling us what it does 
might help. What does the Splus manual have to say about it?

I'm guessing R's write.table might be of use.

  Assuming its exportData that has you stuck - the other bits should 
allwork in R no problem, all it does is construct a path from parts of 
the MU.Cost object.

This particular call to exportData is probably equivalent in effect to
the R call:

write.table(MU.Cost, 
	file = paste("C:/RAUDSL/S",
			    as.character(MU.Cost$Run.Id[1]),
				".",as.character(MU.Cost$MU.Id[1]),
				".MU.PRICE.OUTPUT.txt", sep=""),
	append = FALSE)

as Barry sort of guesses, but in general exportData handles a wide
variety of data export facilities, including writing to odbc connexions,
so other uses of exportData would need the RODBC library in R and
functions like sqlSave or sqlUpdate.

write.table is also an S-PLUS function as well, but exportData is
generally a whole lot faster.
