[R] Package 'coin' - How to extract rho

Dear Jim,

Many thanks for following up on this. Sure, I can provide a sample code. At the end of the code you see that I extract the p-value and the test statistic. However, I cannot find the correlation coefficient rho anywhere in the object “r”.



if(!require(pacman)) install.packages("pacman")

pacman::p_load(sn, fGarch, coin)

# Happiness

central_tendency_sim <- 0

dispersion_sim <- 1

skewness_sim <- 1.5

N_sim <- 10000

Happiness <- seq(from = 0,

               to = 10,

               length.out = N_sim)

# City size

central_tendency_sim <- 3

dispersion_sim <- 1

skewness_sim <- 1.5

Citysize <- seq(from = 1,

                to = 5,

                length.out = N_sim)

# create dataframe

datastat <- data.frame(Happiness, Citysize)

# Bootstrapped correlation

r <- spearman_test(Happiness ~ Citysize, data = datastat, distribution = "approximate", alternative = c("two.sided"))

Hi Christine,

I noticed that your question did not receive a reply. As I don't know exactly what you have tried, it is a bit difficult to suggest a solution. If you are still unable to get this to work, could you provide an example of your present code and data if necessary?
