getVar function

Extract variances

Extract variances from an object of class fitMod.

getVar(fitMod, timePoints = names(fitMod), outFile = NULL)

Arguments

• fitMod: An object of class fitMod.
• timePoints: A character or numeric vector indicating the time point(s) for which the variances should be extracted. When using a character string to reference a time point, the value has to be an exact match to one of the existing time points. When using a number it will be matched by its number ("timeNumber") in the timePoints attribute of the TP object.
• outFile: A character string indicating the .csv file to which the results should be written. If NULL no file is written.

Returns

A data.frame with variances per time point.

Examples

## Using the first example dataset (PhenovatorDat1):
phenoTP <- createTimePoints(dat = PhenovatorDat1,
                            experimentName = "Phenovator",
                            genotype = "Genotype",
                            timePoint = "timepoints",
                            repId = "Replicate",
                            plotId = "pos",
                            rowNum = "y", colNum = "x",
                            addCheck = TRUE,
                            checkGenotypes = c("check1", "check2",
                                               "check3", "check4"))

## Fit a SpATS model on few time points.
modPhenoSp <- fitModels(TP = phenoTP,
                        trait = "EffpsII",
                        timePoints = c(1, 6, 20))

## Extract the variances for all available time points.
getVar(modPhenoSp)
