polyserial correlations not working in correlation()

[shirdekel]

library(correlation)

d <- data.frame(
  x = sample(1:5, 20, TRUE),
  y = as.ordered(sample(letters[1:5], 20, TRUE))
)

# Works

cor_test(d, "x", "y", method = "polychoric")
#> Parameter1 | Parameter2 |  rho |        95% CI | t(18) |     p

#> Observations: 20

# Doesn't work

correlation(d, method = "polychoric")

Less important but perhaps related, why do I need to set include_factors=TRUE for correlation() and not for cor_test()?

[briana-new]

Has this issue been addressed? I am also experiencing issues with the polyserial calculation using correlation(). Not sure if it is a me issue or a bug

[mattansb]

This issue has not yet been addressed - a major update to the package is in the works for this coming year (that will also address this issue) and all efforts are going towards that.
