基于R计算皮尔逊相关系数

基于R计算皮尔逊相关系数

函数

基本基本函数 cor.test

两组数据读入

x=read.csv("1.csv",header = T)

y=read.csv("2.csv",header = T)

计算

cor.test(1,2,method="pearson")

结果

Pearson's product-moment correlation

data:  1 and 2
t = 841, df = 34, p-value <0.0000000000000002
alternative hypothesis: true correlation is not equal to 0
95 percent confidence interval:
 1 1
sample estimates:
cor 
  1
