This is the back-end for the functions plotSlopes and plotCurves. Don't use it directly.
plotFancy(newdf, olddf, plotx, modx, modxVals, interval, plotPoints, legendArgs, col = NULL, llwd = 2, opacity, ...)
newdf |
The new data frame with predictors and fit, lwr, upr variables |
olddf |
A data frame with variables(modxVar, plotxVar, depVar) |
plotx |
Character string for name of variable on horizontal axis |
modx |
Character string for name of moderator variable. |
modxVals |
Values of moderator for which lines are desired |
interval |
TRUE or FALSE: want confidence intervals? |
plotPoints |
TRUE or FALSE: want to see observed values in plot? |
legendArgs |
Set as "none" for no legend. Otherwise, a list of arguments for the legend function |
col |
requested color scheme for lines and points. One per value of modxVals. |
llwd |
requested line width, will re-cycle. |
