It is trivial to generate a csv using almost every programming language, including R. They can be easily edited using any text editor. Wouldn’t it be nice to be able to directly download a CSV file into R? When I manually download, a file like this is generated "MDG_Export_20150821_224828123.csv". The server generates a new file name (MDG_Export + date + time). Is there anyway I can download this from my R program because the manual download is not an option in my project? Thank you for your help.

Even a simple .csv file can be imported using a range of methods, with implications for computational efficiency. This section looks at three approaches: base R’s reading functions such as read.csv, which are derived from read.table; the data.table approach, which uses the function fread; and the new readr package Note to self – Remember to serialize R objects as RDS files when it makes sense.
