Handle Missing Values in Objects

Description

These methods are useful for dealing with NAs in e.g., source_spct, response_spct, filter_spct and reflector_spct.

Usage

## S3 method for class 'source_spct'
na.omit(object, na.action = "omit", ...)

## S3 method for class 'response_spct'
na.omit(object, na.action = "omit", ...)

## S3 method for class 'filter_spct'
na.omit(object, na.action = "omit", ...)

## S3 method for class 'reflector_spct'
na.omit(object, na.action = "omit", ...)

## S3 method for class 'cps_spct'
na.omit(object, na.action = "omit", ...)

## S3 method for class 'raw_spct'
na.omit(object, na.action = "omit", ...)

## S3 method for class 'chroma_spct'
na.omit(object, na.action = "omit", ...)

## S3 method for class 'generic_spct'
na.exclude(object, na.action = "exclude", ...)

Arguments

Details

If na.omit removes cases, the row numbers of the cases form the "na.action" attribute of the result, of class "omit".

na.exclude differs from na.omit only in the class of the "na.action" attribute of the result, which is "exclude".

Note

na.fail and na.pass do not require a specialisation for spectral objects. R's definitions work as expected with no need to override them.

Examples

my_sun.spct <- sun.spct
my_sun.spct[3, "s.e.irrad"] <- NA
my_sun.spct[5, "s.q.irrad"] <- NA
na.omit(my_sun.spct)
na.action(na.omit(my_sun.spct))
