frfast
objects with the base graphicsUseful for drawing the estimated regression function,
first and second derivative (for each factor's level). Additionally, with the
diffwith
argument it is possible to draw the differences between
two factor's levels.
## S3 method for class 'frfast' plot( x = model, y, fac = NULL, der = NULL, diffwith = NULL, points = TRUE, xlab = model$name[2], ylab = model$name[1], ylim = NULL, main = NULL, col = "black", CIcol = "black", pcol = "grey80", ablinecol = "red", abline = TRUE, type = "l", CItype = "l", lwd = 2, CIlwd = 1, lty = 1, CIlty = 2, cex = 0.6, ... )
x |
|
y |
NULL. |
fac |
Vector which determines the level to take into account
in the plot. By default is |
der |
Number or vector which determines any inference process.
By default |
diffwith |
Factor's level used for drawing the differences respect to the
level specified in the |
points |
Draw the original data into the plot. By default it is
|
xlab |
A title for the |
ylab |
A title for the |
ylim |
The |
main |
An overall title for the plot. |
col |
A specification for the default plotting color. |
CIcol |
A specification for the default confidence intervals plotting color. |
pcol |
A specification for the points color. |
ablinecol |
The color to be used for |
abline |
Draw an horizontal line into the plot of the second derivative of the model. |
type |
What type of plot should be drawn. Possible types are,
|
CItype |
What type of plot should be drawn for confidence intervals.
Possible types are, |
lwd |
The line width, a positive number, defaulting to 1.
See details in |
CIlwd |
The line width for confidence intervals, a positive number, defaulting to 1. |
lty |
The line type. Line types can either be specified as an integer
(0 = blank, 1 = solid (default), 2 = dashed, 3 = dotted, 4 = dotdash,
5 = longdash, 6 = twodash). See details in |
CIlty |
The line type for confidence intervals. Line types can either be specified as an integer (0 = blank, 1 = solid (default), 2 = dashed, 3 = dotted, 4 = dotdash, 5 = longdash, 6 = twodash). |
cex |
A numerical value giving the amount by which plotting symbols
should be magnified relative to the default. See details in |
... |
