Hi, I am relatively new to R. Have scourged the help files and the www but havent been able to get a solution.
I have around 250 csv files, one file for each date. They have columns of all types, numeric, string etc. The name of each file is the date in the form of 'yyyymmdd'. There is no column within the file which helps me identify the date on which the file was generated, only the filename has that info. I am selecting some data (using read.csv.sql) from each file and creating a dataset for each day. Ultimately I will combine all the datasets. I can accomplish the select and combine part, but after combining I wont have a record as to the date corresponding to the data. Hence I want to insert the filename as a column in the respective file to help me in identifying to what date each data row belongs to. Sorry for the long mail, but wanted to make myself clear. Any help would be greatly appreciated.
