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