R help - Dec 2005 - change read.table by scan

Hi all,

Before the amount of data given has grown i was initially using read.table to
load the values inside R.

It was feeding my needs because i could tell read.table h=T, then use attach to
access the values by columns names.

Now it takes 20 seconds to load the data's and the first enhancement i could
do is to win some time on the load of the data's...

How could i use the scan function (which is faster) to build the data as if
i've used read.table("file",h=T) then attach?

/* the code i use actually */
tab<-read.table("blob/data.dat",h=T)
attach(tab)
/* is it possible to produce the same using scan? */


thks all for understanding my question.

guillaume.

read.table _does_ use scan, so why do you claim scan is faster?

There is so much you have not told us that it is impossible to know what 
you want.  Please do read the posting guide and its references and try to 
ask a question that is not predicated on a falsehood.
