R help - Feb 2006 - question about binary data file and data.frame

I have a binary file with data sequence in the order

[age,weight][age,weight] ....

I know the length of the data and I want to load it into a data.frame. of course
a way to do this is to
read age and weight seperately and then use cbin(age,weight) to combine them
into a dataframe, but is there a better
solution?

Thanks in advance!

 What do you mean by 'binary file'?

 How are age and weight encoded in this 'binary file'?

 Is it really an ASCII file? With age and weight separated by commas,
and then age-weight pairs separated by spaces? Are there really square
bracket pairs in there too?

 Or is it really a binary file, a series of 4 or 8-byte binary
representations of age and weight?

 Barry

Each data (edge,weight) is numerical data with type double (4 bytes)

df<-file("d:/sim.data","rb")
age[1]<-readBin(df,double())
weigt[1]<-readBin(df,double())
...
age[10]<-readBin(df,double())
weigt[10]<-readBin(df,double())

it is not asc file.
