strange behaviour read.table and clipboard

PIKAL Petr
Dear all

I used to transfer data from excel to R by simple ctrl-c and read.delim("clipboard") construction. I know it is a bad practice but it is easy and for quick exploratory work it is OK. However after changing to new R devel few days ago I encountered weird behaviour. I tried one or two columns.

In case of 2 columns, header is repeated after 526 items
> mar<-read.delim("clipboard")
> which(mar$a2=="a1")
[1]  525 1051 1577
> diff(which(mar$a2=="a1"))
[1] 526 526
and only first header item is repeated.

In case of one column, header is repeated after 1107 items

> mar<-read.delim("clipboard")
> diff(which(mar$a2=="a2"))
[1] 1107 1107

And all items in object are therefore changed to factor.

BTW, readxl package works on same excel file smoothly.

I will try to download the most recent R version to check it, but it could take some time due to our IT issues.

Best regards
Petr

You haven't posted something that is reproducible.  I don't have Excel,
but I can cut and paste from Libreoffice, and I don't see this.
However, it's not the same spreadsheet as you used, so I wouldn't be
comfortable saying I did what you did.

Please reduce the size of your spreadsheet if you can, and then post
instructions for how to construct it, and what to cut and paste from it.
  Then others can try what you did and see if this is specific to your
machine, to that particular version of R-devel, to Excel, etc.

Re: strange behaviour read.table and clipboard

PIKAL Petr
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
Petr

Thank you for the report, it is a bug in buffering in R (not specific to
