Version 0.7.3
Documentation improvements.
Version 0.7.2
Clean up for CRAN.
Version 0.7.1
Added an error message to `coxsimSpline` if white spaces are not entered before and after equal (=) signs in the `bspline` argument.
Version 0.7
- Added package vignette (partially completed).
- Expanded `coxsimPoly` so that it is capable of simulating other quantities of interest. Also, bug fixes.
- `spin = TRUE` works for quantities of interest when Xj - Xl = 0, i.e. in situations when all of the simulated quantities are 1 (or 0 for First Differences).
- Documentation improvements.
- Bug fixes, including:
- SPIn lower bound for different quantities of interest.
- Fixed an error in the calculation of quantities of interest from Splines.
Version 0.6
- Increased flexibility for setting confidence levels. Now they may be set at any numeric value from 0 through 1.
- Choice of using confidence levels for the middle simulation values or the shortest probability interval.
- Many thanks to Ying Liu. Code from his SPIn function is fundamental for making this possible.
- `qi` now automatically determined by `simGG`.
- `means` argument added to `coxsimLinear` and coxsimInteract`. This allows the user to choose if they would like Hazard Rates to be fitted using the variables (other than the variables of interest) set to their means rather than 0. Note: it does not currently support models that include polynomials created by `I`.
- `means` will be added to the other simulation commands in future versions.
- Minor bug fixes and documentation updates.
Version 0.05
**Major update** to the way simPH plots simulated objects. Instead of using seperate commands for plotting objects of different sim classes it now uses the method `simGG`.
In practical terms this means that you can now just use the command `simGG` rather than the old gg. . . commands.
Version 0.04.62
Minor bug fix for `ci` argument.
Version 0.04.6.1
Minor change: now line drawn.
Version 0.04.6
Standardise how hazard rates are calculated.
Version 0.04.5
Made updates so that the package is compatible with data.table package version 1.8.8.
Version 0.04.4
Minor improvement to ggtvc legend
Version 0.04.3
Minor bug fixes.
Version 0.04.2
Updated the syntax for `simcoxtvc` and `ggtvc` for hazard ratios and stratified hazard rates so that it matches the syntax for the other commands.
Other bug fixes.
Version 0.04.1
Minor bug fix for `ggspline` when `qi == 'First Difference'`.
Version 0.04
Added `coxsimSpline` and `ggspline` to simulate and plot quantities of interest for penalised splines.
Version 0.03.2
Minor bug fixes, documentation improvements for `coxsimInteract`.
Version 0.03.1
Improved error messages in `coxsimInteract` and minor documentation changes.
Version 0.03
Added `coxsimInteract` to simulate quantities of interest for linear multiplicative interactions and `gginteract` for plotting these simulations.
Also made an important fix to how `coxsimLinear` calculates hazard rates and how `gglinear` plots these simulations.
Other documentation fixes.
Version 0.02.2
Minor change to how `coxsimtvc` runs so that it is no longer dependent on **reshape**.
Version 0.02.1
Updated documentation and added the ability to change the smoothing line colour for first difference and relative hazard plots.
Version 0.02
Added functions for simulating and plotting linear non-time-varying hazards.
- `coxsimLinear`: simulates linear non-time-varying hazards
- `gglinear`: plots linear non-time-varying-hazards
Version 0.01
First version, largely ported from simtvc version 0.04 (<http://christophergandrud.github.com/simtvc/>), with the addition of the ability to work with polynomials. This includes two functions
- `coxsimPoly` simulates polynomial relative hazards
- `ggpoly` graphs the simulated polynomial relative hazards
