Hi R-friends
I need to read a big matrix (something like 1024000x1024) into 1000 small
matrices. After that, I need write each small matrix (1024x1024) into a asc
file, putting de index of matrix (1:1000) on the file name.
I´m makint it by a hard and unelegant way:
mat<-scan("file...") # reading list
mat_r001<-matrix(mat[1:1048576],1024,1024) # here I used list positions
mat_r002<-matrix(mat[1048577:2097152],1024,1024)
mat_r003<-matrix(mat[2097153:3145728],1024,1024)
write (mat_r0001, file = "mymat_r0001.txt")
write (mat_r0001, file = "mymat_r0002.txt")
...
write (mat_r0999, file = "mymat_r0999.txt")
write (mat_r1000, file = "mymat_r1000.txt")
rm(mat_r001)
rm(mat_r002).. ... rm(mat_1000)
Helllp, please.
Miltinho :-)
