I am curious about how exactly does the mean parameter in rnorm function work? Because, when I pass rnorm(n = 2, mean = 2), it does fetch me two random numbers (which is understood) but, not sure about the significance of mean value that we are passing as the second parameter. The...
Functions inR主要分三个部分来讲解函数:编写函数所需的基础知识相关语法作用域R语言作用域的规则编写函数所需的基础知识R语言通过function()指令来命名和创建函数。首先要给函数赋值,也就是命名,然后在小括号中写入参数,最后再大括号中写入函数要执行的语句,其基本语法是:f <- func...
mean - an average of n numbers computed by adding some function of the numbers and dividing by some function of n mean value statistics - a branch of applied mathematics concerned with the collection and interpretation of quantitative data and the use of probability theory to estimate population ...
# R program to calculate # Arithmetic mean of a vector # Creating a numeric vector x1 <- c(1, 2, 3, 4, 5, 6) x2 <-c(1.2, 2.3, 3.4, 4.5) x3 <- c(-1, -2, -3, -4, -5, -6) # Calling mean() function mean(x1) mean(x2) mean(x3) 输出: [1] 3.5 [1] 2.85 [...
It works like a pipe, hence the reference to Magritte's famous paintingThe Treachery of Images. What the function does is to pass the left hand side of the operator to the first argument of the right hand side of the operator. In the following example, the data frame iris gets passed ...
