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.

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/.

Installation

You can install the released version of forestmodel from CRAN with:

install.packages("forestmodel")

And the development version from GitHub with:

# install.packages("devtools")
devtools::install_github("NikNakk/forestmodel")

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)))

Specifying the covariates to show:

print(forest_model(coxph(Surv(time, status) ~ ., pretty_lung), 
                   covariates = c("Age", "Sex")))
