Dear developeRs,
I have just discovered a strange feature when assigning some values to
columns of a data frame: The column is matched by partial matching (as
documented), but when assigning a value, a new column with the partial
name is added to the data frame that is identical to the

Hi,
The following was already a topic on r-help, but after understanding what is
going on, I think it fits better in r-devel.
The problem is this:
When a data.frame has another data.frame in it, rbind doesn't work well.
Here is an example:

a=data.frame(x=1:10,y=1:10)
b=data.frame(z=1:10)

Best regards,
