templateCutoff: Query or Set Template Cutoffs

In monitoR: Acoustic Template Detection in R

Description

Use this function to check or change the values of score cutoff in template lists (corTemplateList or binTemplateList objects), scores (templateScores objects), or detections list (detectionList objects).

Usage

templateCutoff(object)
templateCutoff(object) <- value

Arguments

object	A binary or correlation template list (class binTemplateList or corTemplateList).
value	A numeric vector with the new score cutoff.

Details

templateCutoff is an accessor function and templateCutoff <- is a replacement function.
For replacement, the value object should be as long as the number of templates in object (or the number selecting via indexing) unless it is a named vector (see Examples).

Value

For extraction, a numeric vector of the same length as object with score cutoffs. For replacement, the updated object.

Examples

# Load data
data(btnw)
data(oven)

# Write Wave objects to file (temporary directory used here)
btnw.fp <- file.path(tempdir(), "btnw.wav")
oven.fp <- file.path(tempdir(), "oven.wav")
writeWave(btnw, btnw.fp)
writeWave(oven, oven.fp)

# Create four correlation templates
wct1 <- makeCorTemplate(btnw.fp, name = "w1")
wct2 <- makeCorTemplate(btnw.fp, t.lim = c(1.5, 2.1), frq.lim = c(4.2, 5.6), name = "w2")
oct1 <- makeCorTemplate(oven.fp, t.lim = c(1, 4), frq.lim = c(1, 11), name = "o1")
oct2 <- makeCorTemplate(oven.fp, t.lim = c(1, 4), frq.lim = c(1, 11), dens = 0.1, name = "o2")

# Combine all of them
ctemps <- combineCorTemplates(wct1, wct2, oct1, oct2)
ctemps

# Check cutoffs
templateCutoff(ctemps)

# Change all like this 
templateCutoff(ctemps) <- c(0.35, 0.35, 0.35, 0.35)
# or this
templateCutoff(ctemps) <- c(default = 0.35)

# Change select ones like this
templateCutoff(ctemps) <- c(o1 = 0.45, o2 = 0.45)
# or this
templateCutoff(ctemps)[c(3, 4)] <- 0.45

# Could combine these two steps
templateCutoff(ctemps) <- c(default = 0.35, o1 = 0.45, o2 = 0.45)

# Clean up (only because these files were created in these examples)
file.remove(btnw.fp)
file.remove(oven.fp)
