Can convert lotri objects to data-frames similar to the internal
data frame used in nlmixr()
; These can then be converted back with
as.lotri()
Added the ability to add estimates to a lotri object. These
estimates are an attached data.frame
to the original lotri matrix.
You can extract them or drop them with the function lotriEst()
Allow specifying fixed components in lotri()
matrices.
Add cov
, cor
, sd
, var
, and chol
options for matrix
specification. The final matrix will always be the covariance matrix
Add function lotriMatInv()
which takes a symmetric block matrix
and converts it into a list of matrices. An sort of inverse
operation of lotriMat()
Add error for lotri(~c(40))
Added ability to flag fixed
and unfixed
components in a
matrix. Currently lotri
only supports one type.
For the lotriFix
objects, ie those created with population types
of estimates and covariance estimates, allow them to be converted to
an equivalent expression with as.expression()
for the lotri object
and lotriDataFrameToLotriExpression()
for the data.frame
call.=FALSE

unnamed matrix will be returned.$lower
