Examples

# List of parameters
params <- list(
  bins = 30,
  scale = "width",
  adjust = 2,
  position = "stack",
  size = 1.6,
  fill = "#112246"
)

# Search arguments according to geom
match_geom_args(geom = "histogram", args = params)

#> $bins
#> [1] 30
#> 
#> $fill
#> [1] "#112246"
#> 
match_geom_args(geom = "violin", args = params)

#> $scale
#> [1] "width"
#> 
#> $adjust
#> [1] 2
#> 
#> $fill
#> [1] "#112246"
