Hi,
I have a data.frame that I need to construct iteratively.
At the moment, I'm doing:
d<-data.frame(x=c(),y=c(),z=());
# {and, within some loop}
d<-rbind(d,data.frame(x=newx,y=newy,z=newz);
While this works, it is horribly verbose and probably not efficient, either.
My real data.frame has, of course, many more columns, which can be of
different modes.
I vaguely recall that in much earlier R versions the following worked
d[dim(d)[1]+1,]<-c(newx,newy,newz);
but not anymore (both 1.7 and 1.8 give "subscript out of bounds").
Can anyone suggest a more elegant and/or efficient way of achieving this,
please? Cc to this address highly appreciated.
With many thanks,
David.
