## Create a data matrix
X <- matrix(sample(0:9, 15, TRUE), nrow = 3, ncol = 5)

## Add NA
k <- sample(1:15, 3, FALSE)
X[k] <- NA

## Sparsity
sparsity(X)
#> [1] 0

## Quick description

#> 
#> 3 missing values:
#> * 2 observations (67%) contain missing values.
#> * 3 variables (60%) contain missing values.
