Determine if the segment mean indicates an amplification or a deletion

test_cnv(
  values,
  cutoff = c(-0.3, 0.3),
  return_val = "logic",
  to_val = c("Gain", NA, "Loss")
)

`values`	A numeric vector - the log2Ratio values for copy number changes.
`cutoff`	A numeric vector of length 2 - the cutoff for calling amplifications or deletions
`return_val`	A string - if `"logic"`, return `c(-1,0,1)`-based logical value; if `"num"`, return original numeric value; if anything else, return `c("Loss",NA,"Gain")`-based string. Default value is `"logic"`.
`to_val`	A vector - the text return value. Default value is `c("Gain", NA, "Loss")`.
