.`Plot()`

: If a time series is plotted from a x-axis variable that is not of type`Date`

, then, setting`segments=TRUE`

connects the points (which can vanish if`size=0`

), but the line width parameter`lwd`

was previously not responsive in this context.

`Logit(), Regression()`

: For categorical predictor variables, the conversion to indicator variables now happens before the analysis. All analyses are now only of numeric variables so that the correlation matrix, scatterplot matrix, tolerance, and best subset analyses are now conducted for categorical predictor variables.`Logit(), Regression()`
