Objectsget_what.simple_screenr
extracts components from simple_screenr
-class
objects.
## S3 method for class 'simple_screenr' get_what( from = NULL, what = c("ROCci", "isROC"), ..., conf_level = 0.95, bootreps = 4000, se_min = 0.6 )
from |
the |
what |
the (character) name of the component to extract. Valid values
are |
... |
optional arguments to |
conf_level |
(optional) confidence level for |
bootreps |
the number of bootstrap replications for estimation of
confidence intervals for |
se_min |
minimum value of sensitivity printed for

get_what
is provided to enable easy extraction of components for those
who wish to perform computations that are not provided by the
plot
, predict
, print
or summary
methods.
The following values of what
return:
"isROC"
the roc
-class object produced by roc
containing the in-sample (overly optimistic) receiver-operating characteristic.
"ROCci"
a data frame containing cross-validated sensitivities, specificities and their confidence limits, and thresholds.
get_what.simple_screenr
returns (invisibly) the object specified
by what
.
