Mark NA Values by Time and Frequency

Description

Marks values within a soundscape dataframe as NA according to provided time and (optionally) frequency values

Usage

markNA(x, na, by = NULL)

Arguments

`x`	dataframe of soundscape data to mark NAs in
`na`	dataframe listing areas to mark NA. Must have columns `start` and `end` in UTC listing time ranges. Can also have columns `freqMin` and `freqMax` to also have accompanying frequency ranges, otherwise all frequency values within the time range will be set to NA
`by`	optional column name in both `x` and `na` if only certain rows of `na` should apply to certain rows of `x` (e.g. if these contain multiple deployments overlapping in time, a "DeploymentName" column can be used to only mark appropriate times)

Value

same dataframe as x but with some values replaced with NA

naDf <- data.frame(start=min(manta$UTC),
                   end=max(manta$UTC),
                   freqMin=100,
                   freqMax=500)
plotHourlyLevel(manta)
plotHourlyLevel(markNA(manta, na=naDf))
