创建向量的一种方法是使用c()函数(称为“combine”函数)。R 中的 c() 函数将多个值组合成一个向量。在 R 中,此函数只是字母“c”,后跟括号内向量中所需的值,用逗号分隔:c(x, y, z, ...)。 例如,您可以使用c()函数将数值数据存储在向量中。
基于组合变量生成数据汇总,以前称为split-apply-combine。summarize是一个多面手,用于返回自定义范围的汇总统计值。 非标准计算 代码中没有引号包裹的原始名字,这种方式叫做非标准计算(NSE),高效交互使用函数,减少键盘输入,允许Rstudio中自动完成。还是函数名多个_。
stringr:文本操纵的相关函数。 agricolae:用于实验的设计和分析,特别是植物相关的实验。 ape:用于DNA序列分析和进化的流行包。 我们写和活跃地维护了metacoder(Foster, Sharpton, and Grünwald 2017) 和taxa(Foster, Chamberlain, and Grünwald 2018), 因此他们非常依赖于这个基本教程。
