Hi all. I used to use write.table() to write data into file. However , it seems that write.table() waste a lot of memory on caching temporary variables. Thus it ofen fails on writting larg matrix/frame into file. I noticed that write.matrix() may be better. But how could I write the column names and row names into file, such as "date" "buy" "sell", instead of "[,1]" , "[,2]" , "[,3]"? Anyone has some experience about this? Any other functions work better? Thanks in advance. Tiger
