ggmice

Visualizations for mice with ggplot2

Enhance a mice imputation workflow with visualizations for incomplete and/or imputed data. The ggmice functions produce ggplot objects which may be easily manipulated or extended. Use ggmice to inspect missing data, develop imputation models, evaluate algorithmic convergence, or compare observed versus imputed data.

Installation

You can install the latest ggmice release from CRAN with:

install.packages("ggmice")

Alternatively, you could install the development version of ggmice from GitHub with:

# install.packages("devtools")
devtools::install_github("amices/ggmice")

Example

Inspect the missing data in an incomplete dataset and subsequently evaluate the imputed data points against observed data. See the Get started vignette for an overview of all functionalities. Example data from mice, showing height (in cm) by age (in years).

# load packages
library(ggplot2)
library(mice)
library(ggmice)
# load some data
dat <- boys
# visualize the incomplete data
ggmice(dat, aes(age, hgt)) + geom_point()

# impute the incomplete data
imp <- mice(dat, m = 1, seed = 1)
# visualize the imputed data
ggmice(imp, aes(age, hgt)) + geom_point()
