pla.plots: Make plots for parallel line models

Description

Plots of the "restricted" and "unrestricted" fits for parallel line models. Also plots of the model with individual fits for each combination of sample and dose can be displayed, on the scale of observed values, or corrected for the mean of the values for the dilution step. Finally residuals can be plotted in qq-plots (qqnorm), histograms, box-plots, or against dilutions step, sample, repetition, row, column, block, plate, etc.

Usage

pla.plots(dataframe,
          sampleLabels = levels(unlist(dataframe["Sample"])),
          indexOfReference = 1,
          design = "blocks",
          main = "Parallel Line Model",
          setPdf = FALSE,
          pdfName = "PlaPlots.pdf",
          nc = 4,
          mfrow = c(2, nc),
          oma = c(1, 0, 2, 0),
          mar = c(3.5, 3.5, 0, 0) + 0.6,
          joinReplicates = TRUE,
          showRho = FALSE,
          plots = "default",
          xlab = "Log(Dosis)",
          ylab = "Response: Response",
          pch = 14 + as.numeric(unlist(dataframe["Replicate"])),
          cex = 2,
          lwd = 4,
          colTst = "black",
          colRef = "grey",
          colRho = "grey10",
          colNrm = "grey70",
          tests = NULL)

Arguments

dataframe

The data.frame with relevant variables, created by functions data2assayFrame or assayTable2frame - as for

sampleLabels

A vector of character strings giving the labels of the samples, standard and test-samples: "S", "T", "U", ... If data["Sample"] has one of these values, then these rows are used. These labels

indexOfReference

Index of the reference among the samples given by sampleLabels.

design

main

setPdf

If TRUE then PDF graphics is produced in pdfName. This should not be used for Sweave.

pdfName

A character string giving the name of the file for PDF graphics.
