Hello r-help, why call: #---------- outer(1:1000, 1:2, function(r,c) ifelse(m[r,c]<=0,.0001,m[r,c]) ) #---------- for matrix m with only 1000 rows and 2 columns forces my PC to use more than 250Mb(!) of virtual memory? strange...
Um, a strange use of outer. Try m[m <= 0] <- 0.0001 for an efficient solution.
