manage_na {OpenSpecy}

Ignore or Remove NA intensities

Description

Sometimes you want to keep or remove NA values in intensities to allow for spectra with varying shapes to be analyzed together or maintained in a single Open Specy object.

Usage

manage_na(x, ...)

## Default S3 method:
manage_na(x, lead_tail_only = TRUE, ig = c(NA), ...)

## S3 method for class 'OpenSpecy'
manage_na(x, lead_tail_only = TRUE, ig = c(NA), fun, type = "ignore", ...)

Arguments

x

a numeric vector or an R OpenSpecy object

lead_tail_only

logical whether to only look at leading adn tailing values.

ig

character vector, values to ignore

fun

the name of the function you want run, this is only used if the "ignore" type is chosen.

type

character of either "ignore" or "remove".

...

further arguments passed to fun.

Value

manage_na() return logical vectors of NA locations (if vector provided) or an OpenSpecy object with ignored or removed NA values.

OpenSpecy object to be matched with a reference library fill_spec() can be used to fill NA values in Open Specy objects. restrict_range() can be used to restrict spectral ranges in other ways than removing NAs.

Examples

manage_na(c(NA, -1, NA, 1, 10))
manage_na(c(NA, -1, NA, 1, 10), lead_tail_only = FALSE)
manage_na(c(NA, 0, NA, 1, 10), lead_tail_only = FALSE, ig = c(NA,0))
data(raman_hdpe)
raman_hdpe$spectra[[1]][1:10] <- NA

#would normally return all NA without na.rm = TRUE but doesn't here. 
manage_na(raman_hdpe, fun = make_rel) 

#will remove the first 10 values we set to NA
manage_na(raman_hdpe, type = "remove")
