Added error message to extent.of.irregularity for when formula
and/or ncutpts are not specified in the absence of scheduled visit
times
made use of data.table package when lagging variables and adding
censored rows
Bug fixes
extent.of.irregularity previously only allowed the time variable to
be called “time”; this has now been fixed
IrregLong 0.3.3
Minor changes
due to archival of the frailtypack package, frailty models are now
estimated using coxph rather than frailtyPenal
IrregLong 0.3.2
Bug fixes
iiw.weights failed to consider the interval between last observed
visit and end of follow-up time when maxfu was supplied as a single
number. This has been fixed.
IrregLong 0.3.1
Bug fixes
Fixed a coding error that led extent.of.irregularity to fail when
scheduledtimes was provided.
IrregLong 0.3.0
Major changes
Added function (extent.of.irregularity) to provide graphical and
numeric summaries of the extent of irregularity.
Minor changes
Added an option in the Liang function to provide as an argument a
function computing the value of the covariates X for any subject at any
given time t, not just the observation times.
IrregLong 0.2.0
Major changes
When using lagged variable, there is an option to include a value
for the first lagged observation within each subject.
A function (abacus.plot) for producing an abacus plot has been
added.
The Liang model now allows for time-invariant covariates to be
included in the visit process model.
Bug fixes
The documentation (examples and vignette) has been updated to use
dosing by weight in the measurement frequency model.
tinvarcols can be omitted from addcensoredrows, iiwgee, and
iiw.weights if maxfu=NULL.
lagfn and addcensoredrows no longer require subject identifiers to
be numeric.
