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.
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.

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
