res_vs_idv | R Documentation |
Model residuals plotted against the independent variable (IDV).
The residuals can be one of:
RES: model residuals
WRES: weighted model residuals
CWRES: conditional weighted model residuals
EWRES/ECWRES: Monte Carlo based model residuals
NPDE: Normalized prediction distribution error

xpdb |
An xpose database object. |
mapping |
List of aesthetics mappings to be used for the xpose plot
(e.g. |
res |
Type of residual to be used. Default is "CWRES". |
group |
Grouping variable to be used for lines. |
type |
String setting the type of plot to be used. Can be points 'p', line 'l', smooth 's' and text 't' or any combination of the four. |
title |
Plot title. Use |
subtitle |
Plot subtitle. Use |
caption |
Page caption. Use |
tag |
Plot identification tag. Use |
log |
String assigning logarithmic scale to axes, can be either ”, 'x', y' or 'xy'. |
guide |
Enable guide display (e.g. unity line). |
facets |
Either a character string to use |
.problem |
The $problem number to be used. By default returns the last estimation problem. |
quiet |
Logical, if |
... |
Any additional aesthetics to be passed on |
Plots can be customized by mapping arguments to specific layers. The naming convention is layer_option where layer is one of the names defined in the list below and option is any option supported by this layer e.g. point_color = 'blue', smooth_method = 'lm', etc.
point: options to geom_point
line: options to geom_line
guide: options to geom_abline
smooth: options to geom_smooth
text: options to geom_text
xscale: options to scale_x_continuous
or scale_x_log10
yscale: options to scale_y_continuous
or scale_y_log10
Template titles can be used to create highly informative diagnostics plots.
They can be applied to any plot title, subtitle, caption and tag. Template titles
are defined via a single string containing key variables staring with a '@' (e.g. '@ofv')
which will be replaced by their actual value when rendering the plot.
For example ''@run, @nobs observations in @nind subjects'' would become
''run001, 1022 observations in 74 subjects''. The available key variables
are listed under template_titles
.

# Standard residual

# Absolute value of the residuals
