x |
A list of one or more |
which |
Which plots to plot: 1 model, 2 cumulative distribution of residuals.
Default is |
caption |
Overall caption. Values: |
jitter |
Jitter applied to GRSq and RSq values to minimize over-plotting.
Default is |
col.grsq |
Vector of colors for the GRSq plot.
The default is |
lty.grsq |
Line type for the GRSq plot.
Default is |
col.rsq |
Vector of colors for the RSq plot.
Default is |
lty.rsq |
Line type for the RSq plot.
Default is |
col.vline |
A vertical line is drawn for each object
to show which model size was chosen for that object.
The color of the line is |
lty.vline |
Line type of vertical lines (a vertical line is drawn to show the selected model for each object).
Can be a vector.
Default is |
col.npreds |
Vector of colors for the "number of predictors" plot within the model selection plot.
Default is |
lty.npreds |
Line type of the "number of predictors" plot (in the Model Selection plot).
Default is |
legend.text , do.par , trace |
