Dear all I want to put zeros and ones in matrix I have if the values are over a threshold For that I use: origBoolmap<- (origmap>thresh )
origBoolmap <- as.numeric(origmap>thresh ) should do it without need for any other code. Uwe Ligges
origBoolmap[thresh< origmap]<- 1 origBoolmap[thresh>= origmap]<- 0 Could you please tell me if the first line out of the three is useless? I have checked and seems taht I take the same results.
