Matrix "BYTES" size
If all you want are binary 0/1, then look at the 'bit' package which will let you create a vector of bits. Even for your matrix, you will need almost 1GB of memory to store a copy.

Dear R people. I? facing a big problem. I need to create a matrix with 10.000 columns and 750.000 rows. matrix<- as.data.frame(matrix(data=0L, nrow=750000, ncol=10000) as you can see, the data frame has huge dimesions. I was able to find out about thr "L" in data, this way I? telling that my data is "integer" class. By doing this object.size(matrix) tells me that this is half of the matrix when I don? define as integer (L) The data that I?l be filling with my matrix will be 0 and 1, nothing else, so I could use less bytes. so, my cuestion is, How can I create the same matrix but using even less bytes? I?l appreciate if you can help me. Thank you. Lucas ? ? ? ?[[alternative HTML version deleted]]
