Hi!
There seems to be some inconsistency in the following behaviour:
> MYDATA <-
data.frame(b=c("A","B","C"),x=c(1,2,3))
> MYDATA
b x
1 A 1
2 B 2
3 C 3> MYDATAnew <- MYDATA[0:0,]
> MYDATAnew
[1] b x
<0 rows> (or 0-length row.names)> MYDATAnew <- rbind(MYDATA[0:0,],MYDATA)
> MYDATAnew
b x
1 1 1
2 2 2
3 3 3
Does R forget the type of the columns of a data.frame when the
data.frame contains no data??
