sapply() 函数 R实现 tapply() 函数 R实现 apply(), lapply(), sapply(), and tapply() in R 在本文中,我们将了解R 编程语言中的 apply()、lapply()、sapply() 和 tapply() 函数。 apply() 集合是 R 基本包的一部分。这一系列函数帮助我们将某个函数应用于某个dataframe、列表或向量,并根据我们使用...
apply()R语言中的函数用于对数组或矩阵的元素执行数学运算。 用法: apply(x, margin, func) 参数:x:数组或矩阵margin:要应用操作的维度func:要应用的操作 范例1: # R program to illustrate # apply() function # Creating a matrix A = matrix(1:9, 3, 3) print(A) # Applying apply() over row ...

After running the previous R programming syntax the new data frame shown in Table 3 has been created. At this point, you might not see a difference compared to the data frame that we have created in the first example.However, we can see the crucial difference by checking the classes of ...
Advanced programming 在创建一个函数之前,必须拥有一定的R编程经验。如何判断经验是否足够,简单的办法就是检查是否会使用apply系列函数。 apply函数 在R编程中,人们常常讨论的一个问题就是为什么在R中for循环的执行效率那么低。有人认为在R中的for循环的执行效率并不低,如果感受到低的话,那一定是因为使用者编程的问题...
