##### Category:

Data Structures, Summaries, and Visualisations for Missing Data

##### Use-Cases:

Visualization of missing values, descriptive statistics, …

##### Description:

Missing values are ubiquitous in data and need to be carefully explored and handled in the initial stages of analysis. In this vignette we describe the tools in the package naniar for exploring missing data structures with minimal deviation from the common workflows of ggplot and tidy data.

##### Input:

data.frame, vector

##### Example:
library(naniar)

data(airquality)

print("print data set with NAs")

## Replace "NA" values with values 10% lower
## than the minimum value in that variable.
## This is done by calling the geom_miss_point() function
ggplot2::ggplot(airquality,
ggplot2::aes(x = Solar.R,
y = Ozone)) +
geom_miss_point()
