Plot the dataset with marks where there are missing value. It allows to have a quick idea of the structure of missing values (Missing at Random or not for example).
showdata(X = X, what = c("miss", "correl"), pch = 7)

the matrix to analyse (matrix with missing values or correlations matrix) |
what |
indicates what to plot. If |
pch |
for missing, symbol to plot (can set pch="." for large datasets) |
