drplot(drfit) | R Documentation |
+Produce graphics of dose-response data and dose-response relationships +either combined or separately, for one or more substances. +
+ + ++ drplot(drresults, data, dtype, alpha, path, fileprefix, overlay, + postscript, color, colors, fitcolors) ++ + +
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. + |
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. |
