I’m using list.files(path, pattern, full.names = TRUE) to get a list of files in a specific directory.

The files are, by default, sorted alphabetically. Is there any way in R to keep them sorted by date?

    You can use the file.info function to obtain details on your files. Once you have those details, you can sort the files accordingly. For example, 

    details = file.info(list.files(pattern="*.csv"))

    gives a data frame containing, inter alia, modification and creation times. You can sort that data frame however you want. Here I sort according to modification time, mtime:

    details = details[with(details, order(as.POSIXct(mtime))), ]
files = rownames(details)
