Question

我正在读取一个csv文件，该文件由两个来源的两列数据组成。我想找到它们之间的p值，但是，我得到了标题中提到的错误。

library(psych)
RfileX = read.csv(fpath, header = TRUE)
x = as.matrix(RfileX)
a=x[1:52,1]
b=x[1:52,2]
print(corr.test(a,b, adjust = "none"), short = FALSE)

参考数据（Ls是什么意思？，谢谢）

structure(list(A1 = c(2L, 2L, 2L, 3L, 2L, 2L, 2L, 2L, 2L, 3L), 
    B1 = c(3L, 3L, 2L, 3L, 2L, 3L, 3L, 3L, 2L, 2L)), .Names = c("A1", 
    "B1"), row.names = c(NA, 10L), class = "data.frame")

Answer 1

假设psych包。

如果您阅读?corr.test，您会看到前两个参数是：

   x: A matrix or dataframe

   y: A second matrix or dataframe with the same number of rows as
      x

不向量。所以，你应该能够运行corr.test(RfileX, ...)，ala：

library(psych)
set.seed(42)
x <- data.frame(a = sample(2:3, size = 100, replace = TRUE),
                b = sample(2:3, size = 100, replace = TRUE))
print(corr.test(x, adjust = "none"), short = FALSE)
# Call:corr.test(x = x, adjust = "none")
# Correlation matrix 
#      a    b
# a 1.00 0.13
# b 0.13 1.00
# Sample Size 
# [1] 100
# Probability values (Entries above the diagonal are adjusted for multiple tests.) 
#     a   b
# a 0.0 0.2
# b 0.2 0.0
#  To see confidence intervals of the correlations, print with the short=FALSE option
#  Confidence intervals based upon normal theory.  To get bootstrapped values, try cor.ci
#     lower    r upper   p
# a-b -0.07 0.13  0.32 0.2

错误：“1：ncol（y）中的错误：长度为0的参数”，尝试进行相关性分析时
