No

for read.delim header=TRUE is default option.

The mentioned issue starts between R-devel r71964 and r73003

I cannot narrow this range as I do not have available other versions between this date range.

I tested other read.* functions and all seems to work as expected.

The problem is connected **only** with reading from clipboard. Maybe it is the issue of Windows, but I cannot see anything weird when copying e.g. from Excel to Notepad

Cheers
