mds 0.3.3

UNDER DEVELOPMENT - FUTURE RELEASE

mds 0.3.2

Implemented Updates

Bugfix - Replaceifelse() calls that returnDates with calls toifelse_cp()

mds 0.3.1

Implemented Updates

General - Explicit declarations ofstringsAsFactors=T in alldata.frame() callsfor cross-version compatibility

mds 0.3.0

Implemented Updates

General - Overall improvement of documentation &detailed descriptions of functions - Input parametercovariates specified indeviceevent() must beeitherfactor ornumeric, no longercharacter. - Input parametermatch_levelsspecified intime_series() must befactor, nolongercharacter. - Add to output ofdefine_analyses() a function for adding dates in the unitsspecified bydate_level anddate_level_n -Deprecateduse_hierarchy parameter intime_series() - Explicit carry-forward of define_analysisid

Covariate Handling - Explicit handling of covariate levelanalysis indeviceevent(),define_analyses(),andtime_series() - Added analysis data frame totime_series() output when covariate analysis is requested -Covariates can now be EITHERfactor ORnumerictypes when defined indeviceevent(). Previously onlycharacters (inferred as factors) werea allowed. - Covariate analysisdefinitions include as a whole (marginal effect) or as a subset by afactor covariate level - Covariate analysis is exempt ifthere is zero variation in the data of the covariate - Restructuredexposure() to handle factors only inmatch_levels.

Implantable Devices / Time In-Vivo Handling - Explicithandling of time in-vivo indeviceevent(),define_analyses(), andtime_series() - Addedanalysis data frame totime_series() output when timein-vivo analysis is requested - CHANGED PARAMETERdeviceevent(implant_days) todeviceevent(time_invivo) and make all downstreamchanges.

To-Do List - Feature allowing total events (conceptof reporting fraction) as an exposure data frame - Facility for handlingmultiple events on the same actual occurrence (such as stroke andbleeding during the same operation) - Explicit implementation of theUnique Device Identifier (UDI) - Implementation of IMDRF coding forproduct malfunctions, patient adverse events, and analysis findings

mds 0.2.1

Implemented Updates

• More descriptivedefine_analyses() andtime_series() outputs, including explicit references todevice, event, and covariate levels.
• Alongside more explicit references, corresponding updates to nLabelsattribute oftime_series()
• Outputs ofdefine_analyses() andtime_series() are clearer about the device and event one-uphierarchy levels
• Updatedplot() method to support updates todefine_analyses() andtime_series()

#mds 0.2.0

Implemented Updates

• Allow for list variable type indeviceevents()descriptors argument
• Wrotetime_series() examples in documentation &provided sample time series dataset calledmds_ts
• Better cross-referenced and linked documentation
