effectsize issue with wilcox.test when named the same as variable

[rempsyc]

Maybe this is expected but it seems like the name of the object creates a conflict if it is the same as the variable (can close if expected).

x <- c(1.83,  0.50,  1.62,  2.48, 1.68, 1.88, 1.55, 3.06, 1.30)
y <- c(0.878, 0.647, 0.598, 2.05, 1.06, 1.29, 1.06, 3.14, 1.29)
z <- wilcox.test(x, y, paired = TRUE)

# Works
effectsize::effectsize(z)
#> r (rank biserial) |       95% CI
#> --------------------------------
#> 0.78              | [0.30, 0.94]

# Fails
x <- z
effectsize::effectsize(x)
#> Error: Unable to retrieve data from htest object.
#>   Try using 'rb()' directly.

This is expected - insight::get_data() uses the names stored in the htest.

x <- c(1.83,  0.50,  1.62,  2.48, 1.68, 1.88, 1.55, 3.06, 1.30)
y <- c(0.878, 0.647, 0.598, 2.05, 1.06, 1.29, 1.06, 3.14, 1.29)
z <- wilcox.test(x, y, paired = TRUE)

insight::get_data(z)
#>        x y
#> 1  1.830 1
#> 2  0.500 1
#> 3  1.620 1
#> 4  2.480 1
#> 5  1.680 1
#> 6  1.880 1
#> 7  1.550 1
#> 8  3.060 1
#> 9  1.300 1
#> 10 0.878 2
#> 11 0.647 2
#> 12 0.598 2
#> 13 2.050 2

#> 15 1.290 2
#> 16 1.060 2
#> 17 3.140 2
#> 18 1.290 2

x <- z
insight::get_data(z) # No longer works.
#> NULL
insight::get_data(x)
#> NULL

(Are you beginning to see that the htest class is 💩? Honestly, it's a miracle it works as good as it does...)

Haha, thanks for clarifying this! Good reference for the future.
