Rubberband baseline correction
Rubberband baseline
spc.rubberband(spc, ..., upper = FALSE, noise = 0, spline = TRUE)
spc |
hyperSpec object |
... |
further parameters handed to |
upper |
logical indicating whether the lower or upper part of the hull should be used |
noise |
noise level to be taken into account |
spline |
logical indicating whether the baseline should be an interpolating spline through the support points or piecewise linear. |
Baseline with support points determined from a convex hull of the spectrum.
Use debuglevel >= 1 to obtain debug plots, either directly via function argument or by setting hyperSpec's debuglevel option.
