missingness | R Documentation |
Finds the percent of NAs in a vector or in each column of a dataframe or matrix or in a vector. Possible mis-coded missing values are searched for and a warning issued if they are found.
missingness( d, return_df = TRUE, to_search = c("NA", "NAs", "na", "NaN", "?", "??", "nil", "NULL", " ", "") )
d |
A data frame or matrix |
return_df |
If TRUE (default) a data frame is returned, which generally makes reading the output easier. If variable names are so long that the data frame gets wrapped poorly, set this to FALSE. |
to_search |
A vector of strings that might represent missingness. If
found in |
A data frame with two columns: variable names in d
and the
percent of entries in each variable that are missing.

d <- data.frame(x = c("a", "nil", "b"), y = c(1, NaN, 3), z = c(1:2, NA)) missingness(d) missingness(d) %>% plot()
