Hello R-ren I have a list of csv files in a folder which are labelled essentially in this way (actual data has scores of files) F010116, F020116, F030116 G020116, G030116, G040116, G 050116 H020116, H030116 where F G and H are engines I've got data from and the numbers are the dates. I can manually make a "register" to create a paste label of each engine and the dates for which I have data, which, as in the example, are not the same for each engine, but I am wondering whether there's any way of getting R to read the labels from the folder so that it can then loop through successive engines and dates without being explicitly told what labels it will need to upload each csv file in turn If anyone has ideas I'd be grateful Thanks,Nick

Subject: [R] reading file labels into R
Hello R-ren I have a list of csv files in a folder which are labelled
essentially in this way (actual data has scores of files)
F010116, F020116, F030116
G020116, G030116, G040116, G 050116
H020116, H030116
where F G and H are engines I've got data from and the numbers are the
dates. I can manually make a "register" to create a paste label of each engine
and the dates for which I have data, which, as in the example, are not the
same for each engine, but I am wondering whether there's any way of
getting R to read the labels from the folder so that it can then loop through
successive engines and dates without being explicitly told what labels it will
need to upload each csv file in turn
If anyone has ideas I'd be grateful
Thanks,Nick
