Sorting problem
Sys.setlocale(,"C") x1 <- as.character(date()) # I use date to record the time, and save it to sqlite database, to it converted to character x1_2 <- strptime(x1, "%a %b %d %H:%M:%S %Y") x2 <- as.character(date()) x2_2 <- strptime(x2, "%a %b %d %H:%M:%S %Y") X<-c(x1_2,x2_2) order(X) ## I want to get the permutation other than the sorted vector. ## order(X) works in windows but not Linux. any alternative way to the the permutation?
