This function plots a grid of histograms (for continuous variables) and bar plots (for categorical variables) and labels it with the proportion of missing values in each variable.

plot_all(data, nrow = NULL, ncol = NULL, fill = grDevices::grey(0.8),
border = "black", allNA = FALSE, idvars = NULL, xlab = "",
ylab = "frequency", ...)

## Arguments

optional; number of rows in the plot layout; automatically chosen if unspecified

ncol

optional; number of columns in the plot layout; automatically chosen if unspecified

fill

xlab

labels for the x- and y-axis

ylab

labels for the x- and y-axis
