You can keep each dataframe as a separate file and process them that way.
You can look into storing in a relational database or using filehash. It
all depends on how you want to process the data later.

Hi,
I currently combine multiple processed data (data frame) into a list and
save the list as .rda using the save command. When new data come, I load
the rda file, process the new data into a data frame, append the data
frame to the end of the list, and save the whole list to the disk. The
loading and saving steps are quite time consuming. Since I don't need to
change the old data in the list when new data come, I wonder if there is
an efficient way to update the rda efficiently, e.g. appending the new
data to the rda file directly without loading the whole rda file?
Any suggestions would be appreciated.
thanks
Jeff
