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 ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
