## Version 1.2.3
- Minor changes to `SurvExpand` to work with dplyr 0.3.
- Now requires dplyr 0.3.
- coxsim objects now also given the class `data.frame`.
- No longer depends on plyr.
## Version 1.2.2
- Added `PartialData` argument to `SurvExpand`. The argument allows the user to
determine whether or not to only keep the expanded data needed to find the Cox
partial likelihood.
- Made `MinMaxLines` a top level function that is useful for returning basic
summary statistics from coxsim constricted simulation intervals. Using the
argument `clean = TRUE` returns the simulations' medians, the minimum and
maximum of the constricted intervals (as set in the `coxsim` call) and the lower
and upper 50% of the constricted intervals.
- `MinMaxLines` also now relies on *dplyr* rather than *plyr*. This improves
performance.
## Version 1.2.1
- Minor documentation improvements.
## Version 1.2
- !!!! `smoother` argument for `simGG` is deprecated. Use `method` instead.
The functionality is exactly the same. !!!!
- `tvc` now accepts a vector of variable names.
- jss-example demo added.
- simPH-overview vignette added.
- `extremesDrop` argument added to `coxsim` functions. This drops simulated
quantity of interest values that are Inf/NA/NaN/>1000000. These can create
problems with plotting and finding the `spin`.
- Small utility `setXl` created that makes it easier to set `Xl` values.
- Automatic `bspline` cleaning features added for `coxsimSpline`.
- Minor documentation improvements.
- Internal code cleaning.
## Version 1.1.1
- `coxsimPoly` is able to simulate quantities of interest for only the polynomial
terms without the linear component. Feature request from Mattia Valente.
- Minor error message improvements.
## Version 1.1
- Added `SurvExpand` for converting a data frame of non-equal interval continuous
observations into equal interval continuous observations. This is very useful if
you intend to create time interactions. Thanks to Mintao Nie and an anonymous
reviewer for the suggestion.
- Roxyegen documentation improvements.
## Version 1.0
- Added `type` argument to `simGG.spline`. Allows the user to plot using `points`,
`ribbons`, or `lines`. NOTE: the `ribbons` standalone argument is depricated.
- Added `SmoothSpline` argument to `simGG.simspline` to use smoothing splines on
the simulations. Creates a smoother graph.
- Uses `mvrnorm` from the `MASS` package instead of `rmultnorm` to draw the
simulations.
- Documentation and other internal improvements.
## Version 0.8.6
- Documentation improvements.
## Version 0.8.5
- Added the ability to choose whether or not to exponentiate marginal effects for `coxsimInteract` with the `expMarg` argument.
## Version 0.8.4
- Minor bug fix for `simGG.siminteract`.
## Version 0.8.3
- License change and minor message changes.
## Version 0.8.2
- Added `legend` argument to allow the user to hide plot legends, when applicable.
- Minor aesthetic updates and documentation clarifications.
## Version 0.8.1
- Minor changes for CRAN check.
## Version 0.8
- Added the argument `ribbons` to the simGG method. This produces a plot with
shaded areas ('ribbons') for the minimum and maximum simulation values as well
as the central 50% of this area. It also plots a line for the median value of
this area. (Thanks to Jeff Chwieroth for the suggestion.)
- Internal improvements to minimise the size of simulation output objects and
improve performance if qi = "Hazard Rate".
- A number of bug fixes.
## 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
separate 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
(), 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
