Sorting in R programming is easy. The order function’s default sort is in ascending order (sort values from lowest to highest value). A quick hack to reverse this is to add a minus sign to the sorting variable
sort(vec1) # ascending sort 升序 sort(vec1, decreasing = TRUE) # Descending sort 降序 1. 2. 或者 vec1[order(vec1)] # ascending sort vec1[rev(order(vec1))] # descending sort 1. 2. 自定义向量排列 seq(1, 10, by = 2) # diff between adj elements is 2 相邻元素差为2 seq(1, ...
