R devel - Aug 2017 - strange behaviour read.table and clipboard

Hi Duncan

The simples spreadsheet is:

Put a name in the cell, let say "a1"
Put number e.g. 1 below "a1"
Copy the number to enough rows
Select this column and press ctrl-c

result is
> temp<- read.delim("clipboard")
> str(temp)
'data.frame':   1513 obs. of  1 variable:
 $ a1: Factor w/ 2 levels "1","a1": 1 1 1 1 1 1 1 1 1 1
...
> which(temp$a1=="a1")
[1] 1365

R-devel 2015 (69443) works as expected so it started a believe around May or
June this year, when I installed new R version.

I hope it could help to trace the problem. If I can help any further, let me
know.

Best regards
Petr

To make this much easier to diagnose,
use something like

  str(ll <- readLines("clipboard"))

and do this both in R 3.4.1 (or R 3.4.1 patched) and R-devel.
(very easy if you use Emacs ESS also on Windows and have several
 versions of R installed)

I just did that and both versions of R behaved identically,
i.e., returned the same 'll'

(I've tried with different versions of Copy regions from excel;
 my version of Windows (2008 Server R2, fully uptodate with
 updates) is very different than yours; Office is said to be
 Office 2013).

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
