Compare the occurence of missing values in all variables by each other. Suggest limit the number of variables to a maximum of around six. Dependent and explanatory are for convenience of variable selection, are optional, and have no other specific function.

missing_pairs(.data, dependent = NULL, explanatory = NULL,
  use_labels = TRUE, title = NULL, position = "stack",
  showXAxisPlotLabels = TRUE, showYAxisPlotLabels = FALSE)

Arguments

.data

Data frame.

dependent

Character vector. Optional name of dependent variable.

explanatory

Character vector. Optional name(s) of explanatory variables.

use_labels

Use variable label names in plot labelling.

title

Character vector. Optional title for plot.

position

For discrete variables, choose "stack" or "fill" to show counts or proportions.

showXAxisPlotLabels

Show x-axis plot labels.

showYAxisPlotLabels

Show y-axis plot labels.

Value

A plot matrix comparing missing values in all variables against each other.

Examples

# NOT RUN {
explanatory = c("age", "nodes", "age.factor", "sex.factor", "obstruct.factor", "perfor.factor")
dependent = 'mort_5yr'
colon_s %>%
  missing_pairs(dependent, explanatory)
# }
