Fill missing intensities in a chromatogram
imputeChromatogram( chromatogram, method = "spline", polyOrd = 4, kernelLen = 9, splineMethod = "fmm" )
chromatogram |
(data-frames) first column is time, second column is intensity. |
method |
(string) must be either "spline", "sgolay" or "linear". |
polyOrd |
(integer) must be less than kernelLen. |
kernelLen |
(integer) must be an odd integer. |
splineMethod |
(string) must be either "fmm" or "natural". |
(dataframe) has two columns:
time |
(numeric) |
intensity |
(numeric) |
