Use names of named vectors for plotting

[mattansb]

library(ggeffects)

fit <- lm(mpg ~ hp * drat, data = mtcars)

This function returns a named vector

ZZZ <- function(x) {
  c(A = median(x) - 2,
    B = median(x) + 2)
}

ZZZ(rnorm(4))
#>         A         B 
#> -1.377492  2.622508

Would be nice if these names were used in the plot’s legend… (:

plot(ggpredict(fit, terms = c("hp", "drat [ZZZ]")))
#> Loading required namespace: ggplot2

Same for a vector

CCC <- c(O = -9, zap = 20) 
plot(ggpredict(fit, terms = c("hp", "drat [CCC]")))

This one is harder than expected...
