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
