var.equal in t_test() can only be used with explicit TRUE/FALSE

[juliuspfadt]

I came upon this trying to implement things for @jomulder in JASP. It seems the way some arguments are passed in t_test() (

bain/R/t_test_wrapper.R

Line 70 in 6c4eeaa

var_eq <- cl[["var.equal"]]

) does not allow any statements that need "evaluation". My example:

dt <- read.csv("https://raw.githubusercontent.com/jasp-stats/jasp-desktop/development/Resources/Data%20Sets/debug.csv")
options <- list(variances = "equal")
bain::t_test(dt$contNormal, dt$contBinom, var.equal = options[["variances"]] == "equal")

varEqual <- options[["variances"]] == "equal"
bain::t_test(dt$contNormal, dt$contBinom, var.equal = varEqual)

neither of the two ways to pass a boolean to the function works. I think it should.

Thank you for bringing this to my attention Julius! I agree, but do you have a handle on how to fix it?

[juliuspfadt]

when I put var_eq <- eval(cl[["var.equal"]]) for the line I linked, it works for me.

Hmm. I wonder if that would cause problems under other conditions. An explicit eval() call evaluates just that one argument in the parent environment.

I can't think of any conditions, but I also only used this in this very specific instance. but how about evaluating all calls like var_eq <- eval.parent(cl[["var.equal"]])
