lstat: Descriptive statistics for lisst objects

In AlexCast/lisst: Functions for manipulation of the Laser In-Situ Scattering and Transmissometry (LISST) data

Description

The functions calculate the average or the median per variable of a lisst object, for the whole data or in intervals. The dispersion of the dataset or intervals is also retrieved and stored.

Usage

lstat(x, brks, fun = "mean", ...)

## S3 method for class 'lisst'
mean(x, ...)

## S3 method for class 'lisst'
median(x, ...)

## S3 method for class 'lisst'
sd(x, ...)

Arguments

x	A lisst object.
brks	A vector with the breaks (intervals) for the aggregation. See details.
fun	A function to perform the aggregation (mean, median, sd). Defaults to mean.
...	Arguments to be passed to aggregation functions.

Details

The breaks (intervals) are passed directly to the subset function, so must now be supplied in final form.

The resulting time indexing will always be the average of the time of the imput records. In the case of aggregation by depth, time indexing will most likelly not be regular or monotonic. In these cases, plot functions that can have different ordinates should always be by 'depth'.

Methods (by generic)

• mean: Compute the mean for lisst objects

• median: Compute the median for lisst objects

• sd: Compute the median for lisst objects

Examples

mean(donkmeer_bin)

median(donkmeer_bin)

sd(donkmeer_bin)
