Adds variable of interest to the Recipe
Usage
add_var(rec, var_info)
# S4 method for class 'Recipe'
add_var(rec, var_info)
# S4 method for class 'PrepRecipe'
add_var(rec, var_info)Examples
data(metaHIV_phy)
## Define recipe
rec <- recipe(metaHIV_phy)
## add var info
rec <- add_var(rec, var_info = "RiskGroup2")
rec
#> ── DAR Recipe ──────────────────────────────────────────────────────────────────
#> Inputs:
#>
#> ℹ phyloseq object with 451 taxa and 156 samples
#> ℹ variable of interes RiskGroup2 (class: character, levels: hts, msm, pwid)
#> ✖ undefined taxonomic level. Use add_tax() to add it to Recipe!

## add var info to a prep-recipe returns an error
