Forest Plots from Regression Models

Produces forest plots using 'ggplot2' from models produced by functions such as stats::lm(), stats::glm() and survival::coxph().


forestmodel

This is an R package to generate forest plots of the coefficients of models produced by lm, glm, survival::coxph, etc.

The main function is forest_model, with a helper function default_forest_panels to produce the necessary panels data.frame.

Example

library("forestmodel")
library("survival")
library("dplyr")
pretty_lung <- lung %>%
  transmute(time,
            status,
            Age = age,
            Sex = factor(sex, labels = c("Male", "Female")),
            ECOG = factor(lung$ph.ecog),
            `Meal Cal` = meal.cal)
 
print(forest_model(coxph(Surv(time, status) ~ ., pretty_lung)))

Installation

The package can be installed using install.packages. It needs Hadley Wickham's broom, dplyr, gpplot2 and lazyeval packages.

Development takes place on the github repository https://github.com/NikNakk/forestmodel/.

Build Status

News

forestmodel 0.4.3 (2017-04-16)

  • Fixed a bug in forest_model which meant that non-synatic variable names (e.g. with spaces in the title) were dropped from the plot.
  • Now handles character columns as factors.
  • Fixed some incompatibilities with bind_cols in dplyr 0.6.

forestmodel 0.4.2 (2017-04-04)

  • Fixed a couple of issues in panel_forest_plot that produced warnings.

forestmodel 0.4.1

  • Fixed #5 issue regarding coxph models with a single predictor (thanks @vjd) for identifying the bug)

forestmodel 0.4.0 (2015-12-10)

  • Fixed problem with coxph models that used special functions.
  • Changed from forest_breaks to graphics::axisTicks for break calculation.

forestmodel 0.3.3

  • Added n_events and person_time variables to data for display when using a coxph model

forestmodel 0.3.2

  • Now handles logical covariates appropriately
  • Tweaks to break and limit calculation

forestmodel 0.3.1

  • Added option (set as default) to recalcluate panel widths
  • Added function to make custom panels easier to generate (forest_panels)
  • Tidied up parameters to make them more consistent between functions
