Convert the "thickness" attribute of an existing filter_spct object.
Function to set the "thickness" attribute and simultaneously converting the spectral data to correspond to the new thickness.
convertThickness(x, thickness = NULL)
x |
a filter_spct, object_spct, filter_mspct or object_mspct object. |
thickness |
numeric (m) |
For spectral transmittance at a different thickness to be exactly
computed, it needs to be based on internal transmittance. This function
will apply converTfrType() to x if needed, but to succeed
metadata should be available. Please, see convertTfrType.
x possibly with the "thickness" field of the
"filter.properties" attribute modified
if x is not a filter_spct object, x is returned
unchanged. If or x does not have the "filter.properties"
attribute set and with no missing data, x is returned with
Tfr set to NA values.
Other time attribute functions:
checkTimeUnit(),
convertTfrType(),
convertTimeUnit(),
getTimeUnit(),
setTimeUnit()
my.spct <- polyester.spct filter_properties(my.spct) convertThickness(my.spct, thickness = 250e-6)
