derive_var_atoxgr {admiral} | R Documentation |
Derive Lab High toxicity Grade 0 - 4 and Low Toxicity Grades 0 - (-4)
Description
Derives character lab grade based on high and low severity/toxicity grade(s).
Usage
derive_var_atoxgr(
dataset,
lotox_description_var = ATOXDSCL,
hitox_description_var = ATOXDSCH
)
Arguments
dataset |
Input dataset The variables specified by the |
lotox_description_var |
Variable containing the toxicity grade description for low values, eg. "Anemia" |
hitox_description_var |
Variable containing the toxicity grade description for high values, eg. "Hemoglobin Increased". |
Details
Created variable ATOXGR
will contain values "-4", "-3", "-2", "-1" for low values
and "1", "2", "3", "4" for high values, and will contain "0" if value is gradable
and does not satisfy any of the criteria for high or low values. ATOXGR is set to
missing if information not available to give a grade.
Function applies the following rules:
High and low missing - overall missing
Low grade not missing and > 0 - overall holds low grade
High grade not missing and > 0 - overall holds high grade
(Only high direction OR low direction is NORMAL) and high grade normal - overall NORMAL
(Only low direction OR high direction is NORMAL) and low grade normal - overall NORMAL
otherwise set to missing
Value
The input data set with the character variable added
