Dear all,
I have a flat (ASCII) dataset of 130 columns and roughly 250,000 lines. In
theory all the observations should be numeric, but just by visual inspection
I can tell that's not the case. So now I want to count the number of
non-numeric observations by column.
I'm trying to use -infix-, i.e.
infix var1 1 var2 2 .... var130 130 using ../rawdata/raw.txt
Is there a quick way to put each column into a variable (other than typing
all the indivdual variable names and column numbers), and reading in the
dataset only once?
I know I can do sth like
forvalues i=1/130 {
infix var`i' `i' using ../rawdata/raw.txt, clear
sum var`i' *to see how many numeric obs i have
}
but this would mean having to read in a sizeable dataset 130 times which
would take a long time.
thanks a lot,
Radu Ban
