plot.AccurateGLM {aglm}  R Documentation 
Plot contribution of each variable and residuals
Description
Plot contribution of each variable and residuals
Usage
## S3 method for class 'AccurateGLM'
plot(
x,
vars = NULL,
verbose = TRUE,
s = NULL,
resid = FALSE,
smooth_resid = TRUE,
smooth_resid_fun = NULL,
ask = TRUE,
layout = c(2, 2),
only_plot = FALSE,
main = "",
add_rug = FALSE,
...
)
Arguments
x 
A model object obtained from 
vars 
Used to specify variables to be plotted (

verbose 
Set to 
s 
A numeric value specifying 
resid 
Used to display residuals in plots. This parameter may have one of the following classes:

smooth_resid 
Used to display smoothing lines of residuals for quantitative variables. This parameter may have one of the following classes:

smooth_resid_fun 
Set if users need custom smoothing functions. 
ask 
By default, 
layout 
Plotting multiple variables for each page is allowed. To achieve this, set it to a pair of integer, which indicating number of rows and columns, respectively. 
only_plot 
Set to 
main 
Used to specify the title of plotting. 
add_rug 
Set to 
... 
Other arguments are currently not used and just discarded. 
Value
No return value, called for side effects.

Examples
#################### using plot() and predict() ####################
library(MASS) # For Boston
library(aglm)
## Read data
xy < Boston # xy is a data.frame to be processed.
colnames(xy)[ncol(xy)] < "y" # Let medv be the objective variable, y.
## Split data into train and test
n < nrow(xy) # Sample size.
set.seed(2018) # For reproducibility.
test.id < sample(n, round(n/4)) # ID numbders for test data.
test < xy[test.id,] # test is the data.frame for testing.
train < xy[test.id,] # train is the data.frame for training.
x < train[ncol(xy)]
y < train$y
newx < test[ncol(xy)]
y_true < test$y
## With the result of aglm()
model < aglm(x, y)
lambda < 0.1
plot(model, s=lambda, resid=TRUE, add_rug=TRUE,
verbose=FALSE, layout=c(3, 3))
y_pred < predict(model, newx=newx, s=lambda)
plot(y_true, y_pred)
## With the result of cv.aglm()
model < cv.aglm(x, y)
lambda < model@lambda.min
plot(model, s=lambda, resid=TRUE, add_rug=TRUE,
verbose=FALSE, layout=c(3, 3))
y_pred < predict(model, newx=newx, s=lambda)
plot(y_true, y_pred)
