3. I try to convert source code in R to Delphi code... Thank you in advance for your help... nparACT_IS = function(data_hrs, mean_all, bin_hr){ ## ---- IS numerator calculation result_ISnum <- matrix(NA, nrow = 24) n <- nrow(data_hrs) p <- 1440/bin_hr for (h in 1:24){ s <- ceiling(n/p) data_hrs3 <- data_hrs data_hrs3[s*p] <- NA data_hrs3 <- matrix(data_hrs3) hrlydat <- data_hrs3[c(seq(h,nrow(data_hrs3),24)),] hrlymean <- mean(hrlydat, na.rm = T) x <- (hrlymean-mean_all)^2 result_ISnum[h,] <- x } ISnum <- sum(result_ISnum) ISnumerator <- n*ISnum ## ---- IS denominator calculation result_ISdenom <- matrix(NA, nrow = n) for (j in 1:n){ y <- ((data_hrs[j,]-mean_all)^2) result_ISdenom[j,] <- y } ISdenom <- sum(result_ISdenom) ISdenominator <- p*ISdenom ## ----------------------------- IS <- round(ISnumerator/ISdenominator, digits = 2) return_IS <- c(IS, ISdenom, n, p) return(return_IS) },
