Produce the fits from a natural cubic smoothing spline applied to a response in a data.frame
Plots longitudinal data from a Lemna Tec Scananalyzer
Tests if any values in a vector are anomalous in being outside specified limits
Adds the fits after fitting a natural cubic smoothing spline to subsets
of a response to a data.frame
Imports an Excel imaging file and allows some renaming of variables
Replaces the values in a vector with the result of applying an operation to it
and a lagged value
Calculates a single value that is a function of an individual's values for a response over a specified time interval
Calculates the cumulative sum, ignoring the first element if exclude.1st is TRUE
Selects a subset of variables using Principal Variable Analysis (PVA)
Adds the factors and covariates for a blocked, split-plot design
Forms a subset of responses in data that contains their values for the nominated times
Compares, for a set of specified values of df, a response and the smooths of it, possibly along with growth rates calculated from the smooths
Selects a subset of variables observed within a specified time interval using Principal Variable Analysis (PVA)
Calculates growth rates (AGR, PGR, RGRdiff) between pairs of values in a vector
Calculates a single value that is a function of an individual's values for a response
Calculates the growth rates for a specified time interval by taking weighted averages of growth rates for times within the interval
Data for an experiment to investigate a rice germplasm panel
Calculates and plots correlation matrices for a set of responses
A small data set to use in function examples
Calculates the growth rates for a specified time interval
Calculates water use indices (WUI) over a specified time interval to a
data.frame
Creates a data.frame formed by applying, for each response, a binary operation
to the paired values of two different treatments
Plots the hour of the day carts are imaged against the days after planting
(or some other number of days after an event)
Selects a set variables to be retained in a data frame of longitudinal data
Adds the growth rates calculated continuously over time for subsets
of a response to a data.frame
Calculates the Water Use Index (WUI)
Computes a measure of how correlated each variable in a set is with the other variable,
conditional on a nominated subset of them
Identifies anomalous individuals and produces longitudinal plots without them and with just them
