+# Convert vector to factor based on threshold of number of unique levels
+
+This is a wrapper of forcats::as_factor, which sorts numeric vectors
+before factoring, but levels character vectors in order of appearance.
+
+## Usage
+
+``` r
+var2fct(data, unique.n)
+```
+
+## Arguments
+
+- data:
+
+  vector or data.frame column
+
+- unique.n:
+
+  threshold to convert class to factor
+
+## Value
+
+vector
+
+## Examples
+
+``` r
+sample(seq_len(4), 20, TRUE) |>
+  var2fct(6) |>
+  summary()
+#> 1 2 3 4 
+#> 7 5 6 2 
+sample(letters, 20) |>
+  var2fct(6) |>
+  summary()
+#>    Length     Class      Mode 
+#>        20 character character 
+sample(letters[1:4], 20, TRUE) |> var2fct(6)
+#>  [1] c b b a d d c d d c b b c d b b b a a c
