collapse/bind several hyperSpec objects into one object
1 | collapse(..., wl.tolerance = hy.getOption("wl.tolerance"))
|
... |
hyperSpec objects to be collapsed into one object. Instead of giving several arguments, a list with all objects to be collapsed may be given. |
wl.tolerance |
tolerance to decide which wavelengths are considered equal. |
The spectra from all objects will be put into one object.
The resulting object has all wavelengths that occur in any of the input objects,
wl.tolerance
is used to determine which difference in the wavelengths is
tolerated as equal. The returned object has wavelengths rounded according to the
precision indicated by wl.tolerance
.
Data points corresponding to wavelengths not in the original spectrum will be set to NA. Extra data is combined in the same manner.
If the objects are named, the names will be preserved in extra data column $.name
.
a hyperSpec object
C. Beleites
merge
to merge hyperSpec objects that share wavelengths but contain
different spectra, rbind
, and rbind.fill
