getIsoEffD {DVHmetrics}  R Documentation 
Convert given (fractional) dose into a corresponding (fractional) dose for a different total dose / fractionation schedule according to the linearquadratic model.
getIsoEffD(D1=NULL, D2=NULL, fd1=NULL, fd2=NULL, ab=NULL)
## Default S3 method:
getIsoEffD(D1=NULL, D2=NULL, fd1=NULL, fd2=NULL, ab=NULL)
## S3 method for class 'DVHs'
getIsoEffD(D1=NULL, D2=NULL, fd1=NULL, fd2=NULL, ab=NULL)
## S3 method for class 'DVHLst'
getIsoEffD(D1=NULL, D2=NULL, fd1=NULL, fd2=NULL, ab=NULL)
## S3 method for class 'DVHLstLst'
getIsoEffD(D1=NULL, D2=NULL, fd1=NULL, fd2=NULL, ab=NULL)

DVH
methods: Calculate D2
based on D1
, fd1
, fd2
, and ab
. The default method can also calculate fd2
based on D1
, D2
, fd1
, and ab
.
The (vector of) corresponding (fractional) dose value(s). If D
is some kind of DVH
object, the same kind of object is returned with the individual dose values converted to D2
.
