  • The Complete Guide to Crushed Stone and Gravel gra-rock

    2019-11-11 · Crushed stone: If you hear the generic “crushed stone” term, it usually refers to stone that has a mixture of stone dust in it. This type of stone is best used for a base when heavy compaction is needed. As a result, it is typically used for the base of concrete and paving projects, foundations of structures, and driveway bases.R语言-数据整形之aggregate函数 银河统计 博客园,2016-5-25 · R语言中aggregate函数 前言 这个函数的功能比较强大,它首先将数据进行分组(按行),然后对每一组数据进行函数统计,最后把结果组合成一个比较nice的表格返回。根据数据对
