Parameters for feature engineering and scatter correction

bin_width() controls the width of bins in spectral binning. emsc_degree() controls the polynomial degree for EMSC correction. osc_n_components() controls the number of orthogonal components in OSC.

Usage

bin_width(range = c(1, 20), trans = NULL)

emsc_degree(range = c(0L, 4L), trans = NULL)

osc_n_components(range = c(1L, 10L), trans = NULL)

Arguments

range: A two-element vector holding the defaults for the smallest and largest possible values, respectively. If a transformation is specified, these values should be in the transformed units.
trans: A trans object from the scales package, such as scales::transform_log10() or scales::transform_reciprocal(). If not provided, the default is used which matches the units used in range. If no transformation, NULL.

Value

A function with classes "quant_param" and "param".
