## S3 method for class 'GenericDataFile'
equals(this, other, ...)

Arguments

other

The other GenericDataFile to be compared to.

...

Not used.

Details

The two files compared are equal if they have the same pathname.

The two files compared are not equal if:

  • Argument other is not a GenericDataFile, or

  • their file sizes differ, or

  • their file checksums differ.

If none of the above occurs, the two files are considered equal.

Note that subclasses use refined rules.

Value

Returns TRUE if the file equals the other, otherwise FALSE. If FALSE, attributes are added specifying the pathnames of the two files compared, and the reason for them being different.
