Subject: 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.
