Usage

condvis(
  data,
  model = NULL,
  response = NULL,
  sectionvars = NULL,
  conditionvars = NULL,
  predsInit = NULL,
  pointColor = c("steelblue", "grey0"),
  cPlotPCP = FALSE,
  cPlotn = 1000,
  orderConditionVars = "default",
  threshold = 1,
  thresholdmax = NULL,
  linecols = NULL,
  showsim = NULL,
  theta3d = 45,
  phi3d = 20,
  dataplot = "pcp",
  tours = NULL,
  predictArgs = NULL,
  xlim = NULL,
  ylim = NULL,
  zlim = NULL,
  density = FALSE,
  showdata = density == FALSE,
  displayHeight = 950
)

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")
}
