s_compare works for numeric

Code
  res
Output
   [1] "n"            "sum"          "mean"         "sd"           "se"

  [16] "iqr"          "range"        "min"          "max"          "median_range"
  [21] "cv"           "geom_mean"    "geom_mean_ci" "geom_cv"      "pval"

s_compare for numeric does not give p-value when not at least 2 values in each group
