Plot dose-response models

+ + +

Description

+ +

+Produce graphics of dose-response data and dose-response relationships +either combined or separately, for one or more substances. +

+ + +

Usage

+ +
+  drplot(drresults, data, dtype, alpha, path, fileprefix, overlay,
+    postscript, color, colors, fitcolors)
+
+ + +

Arguments

+ + + + + + + + + + + + + + + + + + + + + + + + +
drresults +A data frame as returned from drfit. +
data +A data frame as returned from drdata. If data is to be +plotted, the data frame has to contain at least a factor called +"substance", a vector called "unit" containing the unit used for the dose, +a column "response" with the response values of the test system normalized +between 0 and 1, a column "dose" with the numeric dose values and a factor +called "dosefactor" containing the dose as a factor. If plotting of the data is +not required, data can be set to FALSE. +
dtype +A string describing if the raw data should be plotted ("raw"), or +an error bar should be constructed from the standard deviations of the +responses at each dose level ("std", default value) or from the confidence +intervals ("conf"). Of course, dtype only makes a difference, if a valid data +object has been referenced. +
alpha +The confidence level, defaulting to 0.95, only used if dtype "conf" has been +chosen. +
path +The path where graphic files should be put if any are produced. Defaults +to "./" i.e. the current working directory of R. +
fileprefix +A string which will form the beginning of each filename, if graphic files are +created. Defaults to "drplot". +
overlay +If TRUE, all output will be put into one graph, otherwise a separate graph +will be created for each substance. In the latter case, on-screen display +(postscript=FALSE) only works correctly for data plots. Dose-response models +will all be put into the last graph in this case. +
postscript +If TRUE, (a) postscript graph(s) will be created. Otherwise, graphics will be +displayed with a screen graphics device. +
color +If TRUE, a sensible selection of colors will be attempted. If false, everything +will be drawn in black +
colors +This is a vector of colors, defaulting to 1:8, used for plotting the data. +
fitcolors +Here you can specify a palette for the colors of the dose-response fits. The +default value is "default", which produces rainbow colors. +
+ +

Value

+ + + + +
results +A data frame containing at least one line for each substance. If the data did not +show a mean response < 0.5 at the highest dose level, the modeltype is set to "none". +Every successful fit is reported in one line. Parameters of the fitted curves are only +reported if the fitted EC50 is not higher than the highest dose.
