R does not recognise columns and rows as they are supposed to be
...: 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")

write to M, using row and columns taken from A and B, with values from C
I want to write to M, using row and columns taken from A and B, with values
from C. C is a lot longer than A and B, so only the first 67420 elements of
C are used in my loop.So how can I improve it to take then the next 67420
and write it to new file and so on till the 248th 67420. Many thanks
