This function plots a ggplot to visualize the distribution of NAs across all variables in the data set.
overview_na( dat, yaxis = "Variables", perc = TRUE, row_wise = FALSE, add = FALSE )
dat | Your data set |
---|---|
yaxis | Label of your y axis ("Variables" is default) |
perc | If TRUE (default) plot returns the number of NAs in percentage |
row_wise | If TRUE (FALSE is default) plot return the number of NAs per row |
add | If TRUE (FALSE is default) it generates a new data frame with na_count and percentage share of NAs for each row |
Depending on the selection, the function returns a ggplot figure that presents the distribution of NAs in the data set or adds the information on the row-wise NA share
