Print/plot methods for nmfkc cross-validation objects

Compact print and (for rank sweeps) a score-vs-rank plot with a “Best (Min)” marker, for the objects returned by nmfkc.ecv, nmfkc.cv and nmfkc.bicv.

Usage

# S3 method for class 'nmfkc.ecv'
print(x, ...)

# S3 method for class 'nmfkc.ecv'
plot(x, main = "nmfkc element-wise CV", ylab = NULL, ...)

# S3 method for class 'nmfkc.bicv'
print(x, ...)

# S3 method for class 'nmfkc.bicv'
plot(
  x,
  main = "nmfkc bi-cross-validation",
  ylab = "sigma (held-out RMSE)",
  ...
)

# S3 method for class 'nmfkc.cv'
print(x, ...)

# S3 method for class 'nmfkc.cv'
plot(
  x,
  main = "nmfkc CV: per-fold held-out loss",
  ylab = "objfunc (block)",
  ...
)
