I've searched for several days for an answer to this, and perhaps I'm not asking it the right way when I search, so I thought maybe someone here would have an answer.
I'm using windows 10. If I wanted to save a .csv file, for example, in my working directory, there are at least two ways I know of that the file path can be specified:
data(iris)
###save to a foler called Data in my working directory
#method 1
write.csv(iris, "./Data/iris.1.csv")
#method 2
write.csv(iris, "Data/iris.2.csv")
Both of these work and the file is identical in content and size.
Is there a difference between the two methods? I can't remember the specific instance, but I think I've had errors when using method 2 before, and solved it by using method 1. Do some file extensions or packages require the "./" at the beginning of the file path?
