Arguments

data: the dataset used for the fit. Should not have NAs for response, sectionvars or conditionvars.
model: A fitted model or list of models. May be NULL.
response: name of response variable. If null, tries to extract from model.
sectionvars: names of sectionvars. If null, extracts from data.
conditionvars: names of condition vars. If null, extracts from data.
predsInit: Optionally provide starting value for some predictors. Defaults to medoid.
pointColor: a color, or the name of variable to be used for coloring. If the named variable is numeric, it is first converted to a factor with 3 levels.
cPlotPCP: if TRUE, conditionplots are drawn as a single PCP (for more than two conditionvars)
cPlotn: Defaults to 1000. Shows a sample of this number of points in conditionplots. Non-numeric values are ignored.
orderConditionVars: If supplied, a function to order the Condition Vars
threshold: used for similarity weights, defaults to 1.
thresholdmax: maximum value allowed of threshold.
linecols: vector of colors to be used for fits
showsim: if TRUE, shows sim in conditionplots with points/lines. Defaults to TRUE with 150 or fewer cases.
theta3d, phi3d: Angles defining the viewing direction for 3d surface. theta3d gives the azimuthal direction and phi3d the colatitude. See persp.
dataplot: "pcp" or "pairs". Used when there is no response, or more than two sectionvars.
tours: A list of pre-calculated tours
predictArgs: a list with one entry per fit, giving arguments for CVpredict
xlim: passed on to sectionplot
ylim: passed on to sectionplot
zlim: passed on to sectionplot
density: default FALSE. Use TRUE if model is a density function.
showdata: defaults to density==TRUE. If FALSE, data on section not shown.
displayHeight: supply a value for the display height

Examples

fit <- lm(mpg ~ wt+hp+am, data=mtcars)
if(interactive()){
condvis(mtcars,fit, response="mpg",sectionvars="wt", conditionvars=c("am", "hp"), pointColor ="red")
}
