Obtain a plot of the pattern of missing data and/or return the pattern as a matrix.

md_pattern(
data,
color = c(grDevices::grey(0.1), grDevices::grey(0.7)),
border = grDevices::grey(0.5),
plot = TRUE,
pattern = FALSE,
print_xaxis = TRUE,
ylab = "Number of observations per pattern",
print_yaxis = TRUE,
legend.position = "bottom",
...
)

Arguments

data data frame vector of length two, that specifies the color used to indicate observed and missing values (in that order) color of the grid logical; should the missing data pattern be plotted? (default is TRUE) logical; should the missing data pattern be returned as matrix? (default is FALSE) logical; should the x-axis (below the plot) and y-axis (on the right) be printed? y-axis label the position of legends ("none", "left", "right", "bottom", "top", or two-element numeric vector) optional additional parameters, currently not used

Note

This function requires the ggplot2 package to be installed.

op <- par(mar = c(3, 1, 1.5, 1.5), mgp = c(2, 0.6, 0))
