Extract and set Xpose variable definitions.
This function extracts and set Xpose variable definitions in "xpose.data" objects.
xvardef(x, object) xvardef(object) <- value
x |
The name of an xpose variable (see below). |
object |
An |
value |
A two element vector of which the first element is the name of the variable and the second the column name in the Data slot of the object. |
The Xpose variable definitions are used to map particular variable types to
column names in the data.frame in the Data slot of the "xpose.data" object.
The single-valued Xpose variable definitions are: id, idlab, idv, occ,
dv, pred, ipred, iwres, res. The (potentially) vector-valued Xpose variable
definitions are: parms, covariates, ranpar, tvparms (parameters,
covariates, random effects parameters=etas, typical value parameters). The
default values of these can be found in the createXposeClasses
function.
Returns a string with the name of the data variable defined as the Xpose data variable.
xvardef<-: reset the which column the label dv points to in the Data slot of
the xpose database object

xpdb <- simpraz.xpdb
## get the column name in the Data slot of object xpdb
## corresponding to the label dv
xvardef("dv", xpdb)
## reset the which column the label dv points to in the Data slot of
## object xpdb
xvardef(xpdb) <- c("dv", "DVA")Please choose more modern alternatives, such as Google Chrome or Mozilla Firefox.
