From 699448335d6fc5668b569577cb38a628c258eaec Mon Sep 17 00:00:00 2001 From: ranke Date: Wed, 21 Dec 2005 15:33:22 +0000 Subject: Changed the terminology from EC50 to ED50 reflecting that the package is meant for dose-response analysis in general and not only for concentration-response analysis. This is the first revision that has been prepared with the knowledge of the existence of the drc package for dose-response curve analysis. git-svn-id: http://kriemhild.uft.uni-bremen.de/svn/drfit@48 d1b72e20-2ee0-0310-a1c4-ad5adbbefcdc --- chm/drplot.html | 143 -------------------------------------------------------- 1 file changed, 143 deletions(-) delete mode 100644 chm/drplot.html (limited to 'chm/drplot.html') diff --git a/chm/drplot.html b/chm/drplot.html deleted file mode 100644 index 84cf12e..0000000 --- a/chm/drplot.html +++ /dev/null @@ -1,143 +0,0 @@ -Plot dose-response models - - - - -

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, datacolors, 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 -
datacolors -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 the default palette, if the -number of fits to be plotted is 8 or less. Otherwise, rainbow colors -will be plotted. Unless there is more than one fit per substance to be plotted, -or the number of fits is larger than 8, the fitcolors will match the -datacolors. -
- -

Value

- - - - -
results -You will get plots of data and/or the fitted dose-response curves, on the -screen and/or as postscript files, depending on the parameters. -
- -

Note

- -

-Turn off the colors if you don't like them and don't want to fiddle with -them. Treatment of legends is quite bad. Be sure all devices are closed -(e.g. by calling dev.off()) before calling drplot again. -
