[R] R does not recognise columns and rows as they are supposed to be

[Jonsson]

Dear All,
The code given bellow is to extract  values of one region and write that to
a text file(there are 365 binary files in the directory).
The problem which I am facing is that all my files are binary with size of
360 rows and 720 columns.
I specified that in this line:    file2<-matrix(data=file,ncol=720,nrow=360)
but I got an error : Error in mean(file2[X, Y], na.rm = TRUE) : subscript
out of bounds.
and then I rewrote the above line as
:file2<-matrix(data=file,ncol=360,nrow=720.I put ncol=360 and nrows =720
which is not right.But that worked and I didn't get any error.however,the
results were not correct.
Any help please

dir1<- list.files("C:\\Users\\aalyaari\\Desktop\\New folder
(10)\\Climate_Rad_f_GAMMA_%d.img", full.names = TRUE)
listfile<-dir()
for (i in c(1:365)) {
      conne <- file(listfile[i], "rb")
      file<- readBin(conne, double(), size=4,  n=720*360, signed=T)
     file2<-matrix(data=file,ncol=720,nrow=360)  
	extract[i]<-mean(file2[X,Y],na.rm=TRUE)
      close(conne)
write.table(extract,"C:\\Users\\aalyaari\\Desktop\\New folder
(10)\\sam.txt")}
