Dear All, Using "dist()" function, I have to calculate distance matrix for large dataset (2,00,000*23) but problem of memory issue came. I had already try by break of data into small and this idea is work but take more time, So I want some other which reduce time. Try to help me to solve out using parallel package (ff or others) or any other way. Thank you, Pinkal Patel [[alternative HTML version deleted]]
