Difference in File Referencing

If I have some function that takes as input the path to two files and an integer, what is difference in the following two situations?

Case 1: function("file1.tif", "file2.tif", N)

Case 2: function('file1.tif', 'file2.tif', N)

If I run my code using case two, I get an error about brace indexing later on in the code. Whereas, if I run case 1 it works fine.

Without the Code We Can Only Speculate. But Using "File1.Tif'" generates A String Object While 'File1.Tif' Is A Character Array.

When You Index The String Array Like That:

s = stringObj(1)

You Get A String

And If You Index A Character Array Like That:

c = charVector(1)

You Get A Single Character

Thank you! That explains if perfectly. I didn't include the code as I was more interested in the syntactic difference than the exact specific of this error.
