I tried to read only one file and get some information but this is what I
got:
sam=file("C:\\Users\\2001\\SWdown_200101_01.img", "rb")
file1<- readBin(sam, double(),size=4, n=360*720)
file.info(file1)$size
Error in file.info(file1) : invalid filename argument
dim(file1)
NULL

The trick may be behind not reading the files properly is that all my 365
files donot have the same name. for example:
files from number 1 to number9 are named for the first month:
SWdown_200101_01.img
SWdown_200101_09.img
files from number 10 to number30 are named:
SWdown_200101_10.i

Yes I did so.
Yes the first values are the right ones: - -.
so this meant that I should consider my data as: double/4/little
Is it so?

Yes this helped a lot .
I exactly followed what you suggested:
X<-(82:92) ; Y<-(364:369) # for sellected region
> extract <- double(365)

Sorry, forgot the last line in the op code.
write.table(extract, ...) is called every time through the loop, not just
one time after it. Put it after closing '}'.

Hello,
There are several things with your code, most of which are not errors.
1. X<-c(364:369) ; Y<-c(82:92 and later c(1:365)
Expressions of the form m:n are integer sequences, the c() is not needed.
2. extract<-vector()
First you create the vector, then keep extending it throughout the loop.
