[R] Obtaining exact pattern in list.files()

[Christofer Bogaso]

Hi,

In the list.files() function, there is an argument 'pattern' to locate the
desired files. However I failed to see if I can manage to fetch those files
that having an exact match.

For example, if there are 2 files that contain the expression 'File' and
'Second_File', then I should get the 1st one. However R is returning both
the files.

Any pointer on how to achieve that would be helpful. Thanks,
