[R] Exporting a list of data frames

[Christoph Scherber]

Dear all,

I found one possible solution using a single call to write.table:

# assuming that mylist is a named list of data.frames:
data(Orange)
mylist=list(Orange1=Orange,Orange2=Orange,Orange3=Orange)

sapply(1:length(mylist),
      function(x){
		write.table(
			data.frame(mydf=rep(names(mylist)[[x]],dim(mylist[[x]])[1]),mylist[[x]]),
			sep="\t",append=T,file="My.data.frames.txt")
}
)


Best wishes,
Christoph
