| plot.nlreg.profiles {nlreg} | R Documentation |
These are methods for the function plot for objects
inheriting from class "profile.nlreg" or
"all.profiles.nlreg" .
## S3 method for class 'nlreg.profile':
plot(x, alpha = 0.05, add.leg = FALSE, stats = c("sk", "fr"),
cex = 0.7, cex.lab = 1, cex.axis = 1, cex.main = 1, lwd1 = 1,
lwd2 = 2, lty1 = "solid", lty2 = "solid", cl1 = "blue",
cl2 = "red", col = "black", ylim = c(-3,3), ...)
## S3 method for class 'all.nlreg.profiles':
plot(x, nframe, alpha = 0.05, stats = c("sk", "fr"), cex = 0.7,
cex.lab = 1, cex.axis = 1, cex.main = 1, lwd1 = 1, lwd2 = 2,
lty1 = "solid", lty2 = "solid", cl1 = "blue", cl2 = "red",
col = "black", ylim = c(-3,3), ...)
x |
an object of class profile.nlreg or
all.profiles.nlreg such as generated by a call to
profile.nlreg.
|
nframe |
the number of frames into which to split the graphics device;
only if x is an all.profiles.nlreg object.
|
alpha |
numeric vector with the levels used to read off confidence
intervals; the default is 5% which corresponds to a confidence
level of 1-alpha=0.95.
|
stats |
character value indicating which higher order statistics to plot.
Admissible values are "sk" for Skovgaard's (1996)
proposal and "fr" for Fraser, Reid and Wu's (1999)
approach. The default is "sk".
|
add.leg |
logical value indicating whether a legend should be added to the
plot; only if x is a profile.nlreg object. The
default is FALSE.
|
cex, cex.lab, cex.axis, cex.main |
the character expansions relative to the standard size of the
device to be used for printing text, labels, axes and main title.
See par for details.
|
lwd1, lwd2 |
the line widths used to compare different curves in the same
plot; default is lwd2 = 2 for higher order solutions and
lwd1 = 1 for first order solutions.
|
lty1, lty2 |
line types used to compare different curves in the same plot;
default is "solid" for all statistics.
|
cl1, cl2, col |
colors used to compare different curves in the same plot; default
is cl2 = "red" for higher order solutions, and
cl1 = "blue" for the remaining first order statistics.
The default color of the plot is col = "black".
|
ylim |
a numerical vector with two elements defining the y-axis
range; only if x is a profile.nlreg object.
|
... |
additional graphics parameters. |
No value is returned.
A plot is produced on the current graphics device.
