Hello! I am running a loop (for a range of dates) and in this loop I am reading in different files - based on a date that is part of the file name. However, for some of the dates, I have no file (no way to know which dates). So, when I try to read it in I get an error:
Error in file(file, "rt") : cannot open the connection Question: I'd like to program an if-then statement in my code that says something like this: myfile<-read.csv(myfilename) if "cannot open the connection" - then do X What statement should I use under "if"?
