⚠️There's a newer version (0.1-62) of this package.Take me there.

imageData (version 0.1-61)

Aids in Processing and Plotting Data from a Lemna-Tec Scananalyzer

Description

Note that 'imageData' has been superseded by 'growthPheno'. The package 'growthPheno' incorporates all the functionality of 'imageData' and has functionality not available in 'imageData', but some 'imageData' functions have been renamed. The 'imageData' package is no longer maintained, but is retained for legacy purposes.

Functions in imageData (0.1-61)

WUI

Calculates the Water Use Index (WUI)
calcTimes

Calculates for a set of times, the time intervals after an origin time and the position of each with in that time
designFactors

Adds the factors and covariates for a blocked, split-plot design
RiceRaw.dat

Data for an experiment to investigate a rice germplasm panel
corrPlot

Calculates and plots correlation matrices for a set of responses
cumulate

Calculates the cumulative sum, ignoring the first element if exclude.1st is TRUE
importExcel

Imports an Excel imaging file and allows some renaming of variables
anomPlot

Identifies anomalous individuals and produces longitudinal plots without them and with just them
anom

Tests if any values in a vector are anomalous in being outside specified limits
exampleData

A small data set to use in function examples
PVA

Selects a subset of variables using Principal Variable Analysis (PVA)
intervalGRdiff

Calculates the growth rates for a specified time interval
imagetimesPlot

Plots the position of a time within an interval against the interval for each cart
imageData-pkg

tools:::Rd_package_title("imageData")
intervalGRaverage

Calculates the growth rates for a specified time interval by taking weighted averages of growth rates for times within the interval
intervalValueCalculate

Calculates a single value that is a function of an individual's values for a response over a specified time interval
rcontrib

Computes a measure of how correlated each variable in a set is with the other variable, conditional on a nominated subset of them
splitValueCalculate

Calculates a single value that is a function of an individual's values for a response
splitContGRdiff

Adds the growth rates calculated continuously over time for subsets of a response to a data.frame
probeDF

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
intervalPVA

Selects a subset of variables observed within a specified time interval using Principal Variable Analysis (PVA)
getDates

Forms a subset of responses in data that contains their values for the nominated times
splitSplines

Adds the fits after fitting a natural cubic smoothing spline to subsets of a response to a data.frame
twoLevelOpcreate

Creates a data.frame formed by applying, for each response, a binary operation to the paired values of two different treatments
fitSpline

Produce the fits from a natural cubic smoothing spline applied to a response in a data.frame
longiPlot

Plots longitudinal data from a Lemna Tec Scananalyzer
intervalWUI

Calculates water use indices (WUI) over a specified time interval to a data.frame
longitudinalPrime

Selects a set variables to be retained in a data frame of longitudinal data
GrowthRates

Calculates growth rates (AGR, PGR, RGRdiff) between pairs of values in a vector
calcLagged

Replaces the values in a vector with the result of applying an operation to it and a lagged value
