An object of the "xpose.prefs" class holds information about all the variable and graphical preferences for a particular "xpose.data" object.
Objects can be created by calls of the form
new("xpose.prefs",...)
but this is usually not necessary since the "xpose.prefs"
object is created at the same time as the "xpose.data" object.
Xvardef:Object of class "list"A list with the
Xpose variable defintions. The values of the list
are strings with the name of one or more columns in the data
frames of Data or SData (xpose.data-class).
To get a listing of the current variable definitions in a
particular "xpose.data" object type: object@Prefs@Xvardef on the
command line (object is the name of the xpose.data
object). These definitions have default values that are adjusted
to reflect the contents of the Data slot in the xpose.data object
when the object is initialized. Look in the
createXposeClasses function for the default values.
To access a specific variable defintion, use
object@Prefs@Xvardef[["vardef"]], where vardef is the name
of the Xpose variable. You can also use the utility function
xvardef.
Labels:Object of class "list" A list that
translates column headers in Data and SData to labels to be used
in graphs, e.g. "TIME" to "Time (h)". This is used in the labelling of
axes, for example.
To get a listing of the current labels in a
particular "xpose.data" object type: object@Prefs@Labels on the
command line (object is the name of the xpose.data
object). These definitions have default values that are adjusted
to reflect the contents of the Data slot in the xpose.data object
when the object is initialized. Default Labels that are not
present in the NONMEM table files are deleted and columns that are
present in the table files but that do not have default Label get
a Label that is the same as the column name. Look in the
createXposeClasses function for the default values.
To access a specific variable defintion, use
object@Prefs@Label[["name"]], where name is the name
of the column in the NONMEM table files. You can also use the utility function
xlabel to access the labels.
The label for a particular column can also be changed using the
xlabel function.
Graph.prefs:Object of class "list" This is a
list with graphical parameters for the various elements in the
Xpose graphs.
To get a listing of the current graphical preferences in a
particular "xpose.data" object type: object@Prefs@Graph.prefs
on the command line (object is the name of the xpose.data
object).
Look in the createXposeClasses function for the default
values and some comments.
Miss:Object of class "numeric" This is a
scalar value that indicate missing values in the NONMEM table
files. The default is -99. Can be accessed by
object@Prefs@Miss.
Cat.levels:Object of class "numeric" This
value is used when an "xpose.data" object is created. Any variable
from a NONMEM table file that has fewer than or equal number of
unque value tha Cat.levels are converted to factors. The default
value is 4.
DV.Cat.levels:Object of class "numeric" This
value is used when an "xpose.data" object is created. If a
variable from a NONMEM table file with the name DV has fewer than
or equal number of unque value than DV.Cat.levels are converted to
a factor. The default value is 7.
Subset:Object of class "character or NULL" A
string that indicates the subset of the data to use in a plot. An
example is SEX==1. This string is used by the
Data and SData
functions when
extracting the data to plot from an "xpose.data" object. Note that
it is not used in the subset argument to xyplot. The
value of Subset can be accessed and changed using the
xsubset function.
Gam.prefs:Object of class "list" This is a
list containing preferences for the general additive model (GAM).
To get a listing of the current graphical preferences in a
particular "xpose.data" object type: object@Prefs@Gam.prefs
on the command line (object is the name of the xpose.data
object).
Look in the createXposeClasses function for the default
values, and see also xpose.gam.
