Parameters used to choose what to plot and how. These parameters are given to plot.SCGLR and pairs.SCGLR.
Details
Parameter name can be abbreviated (e.g. pred.col will be understood as predictors.color).
Options can be set globally using options("plot.SCGLR"). It will then provide default values that can be further overriden by giving explicit parameter value.
parameter name
type (default value). Description.
title
string (NULL). Main title of plot (override built-in).
labels.auto
logical (TRUE). Should covariate or predictor labels be aligned with arrows.
labels.offset
numeric (0.01). Offset by which labels should be moved from tip of arrows.
labels.size
numeric (1). Relative size for labels. Use it to globally alter label size.
expand
numeric (1). Expand factor for windows size. Use it for example to make room for clipped labels.
threshold
numeric. All covariates and/or predictors whose sum of square correlations with the two components of the plane lower than this threshold will be ignored.
‘observations’
logical (FALSE). Should we draw observations.
observations.size
numeric (1). Point size.
observations.color
character ("black"). Point color.
observations.alpha
numeric (1). Point transparency.
observations.factor
logical (FALSE). Paint observations according to factor (specify factor).
‘predictors’
logical or array of characters or comma separated string (FALSE). Should we draw predictors and optionally which one (TRUE means all).
predictors.color
string ("red"). Base color used to draw predictors.
predictors.alpha
numeric (1). Overall transparency for predictors (0 is transparent, 1 is opaque).
predictors.arrows
logical (TRUE). Should we draw arrows for predictors.
predictors.arrows.color
string (predictors.color). Specific color for predictor arrows.
predictors.arrows.alpha
numeric (predictors.alpha). Transparency for predictor arrows.
predictors.labels
logical (TRUE). Should we draw labels for predictors.
predictors.labels.color
string (predictors.color). Specific color for predictor labels.
predictors.labels.alpha
numeric (predictors.alpha). Transparency for predictor labels.
predictors.labels.size
numeric (labels.size). Specific size for predictor labels.
predictors.labels.auto
logical (labels.auto). Should predictor labels be aligned with arrows.
‘covariates’
logical or array of characters or comma separated string (TRUE). Should we draw covariates and optionally which one (TRUE means all).
covariates.color
string ("black"). Base color used to draw covariates.
covariates.alpha
numeric (1). Overall transparency for covariates (0 is transparent, 1 is opaque).
covariates.arrows
logical (TRUE). Should we draw arrows for covariates.
covariates.arrows.color
string (covariates.color). Specific color for covariate arrows.
covariates.arrows.alpha
numeric (covariates.alpha). Transparency for covariate arrows.
covariates.labels
logical (TRUE). Should we draw labels for predictors.
covariates.labels.color
string (covariates.color). Specific color for predictor labels.
covariates.labels.alpha
numeric (covariates.alpha). Transparency for covariate labels.
covariates.labels.size
numeric (labels.size). Specific size for covariate labels.
covariates.labels.auto
logical (labels.auto). Should covariate labels be aligned with arrows.
‘factor’
logical or character (FALSE). Should we draw a factor chosen among additionnal variables (TRUE mean first one).
factor.points
logical (TRUE). Should symbol be drawn for factors.
factor.points.size
numeric (4). Symbol size.
factor.points.shape
numeric (13). Point shape.
factor.labels
logical (TRUE). Should factor labels be drawn.
factor.labels.color
string ("black"). Color used to draw labels.
factor.labels.size
numeric (labels.size). Specific size for factor labels.
