Dear all,

Dear all,

I am a relatively new user.
I have an ascii file with 550 rows and 400 columns. The file contain 
values
ranging from 1 to 2000 and some values with -9999.

I want to generate a new file where the -9999 values are replaced with 0 
values, the other values with the 1.0 value.
Do you want to use R for it? If yes you can read the file and set -9999 as 
missing value
see ?read.table

further on you can

change not NA values to 1 by

your.data[!is.na(your.data)] <- 1

and NA values to 0 by

your.data[is.na(your.data)] <- 0

Regards
Petr
What should I do,

Thanks
Taiseer
