In ToshihiroIguchi/calcor: Calculate correlation

calcor package

Automatic judgment of ordinal scale and nominal scale and calculation of p-value from association.

Description

Automatic judgment of ordinal scale and nominal scale and calculation of p-value from association. Calculate the relationship between all order scales and nominal scales for explanatory variables specified in formula form and calculate p-values.

Installation

You can install from R console.

If devtools is not installed on your PC, install devtools with Internet connection.

install.packages("devtools")

Install from GitHub using devtools.

library(devtools)
install_github("ToshihiroIguchi/calcor")

Load the elasticnet package and attach it.

library(calcor)

Examples

We will explain with Fisher's iris as an example. For Sepal.Length that can be treated as an order scale, calculate the p-value of each item from the relation of other items.

result1 <- calcor(Sepal.Length ~ ., iris)

Display a list of p-values calculated by each method. Also, items that could not be calculated are also displayed.

summary(result1)

A bar graph of p-value is displayed by the plot function.

plot(result1)

The correlation is shown in slide show in ascending order of p-value.

slideshow(result1)

For Species that can be treated as an nominal scale, calculate the p-value of each item from the relation of other items.

result2 <- calcor(Species ~ ., iris)
