We at STATWORX work a lot with R and we often use the same little helper functions within our projects. These functions ease our daily work life by reducing repetitive code parts or by creating overviews of our projects. At first, there was no plan to make a package, but soon I realised, that it will be much easier to share and improve those functions, if they are within a package. Up till the 24th December I will present one function each day from
helfRlein. So, on the 7th day of Christmas my true love gave to me…
What can it do?
This little helper counts missing values within a vector.
x <- c(NA, NA, 1, NaN, 0) count_na(x)  3
Internally, there is just a simple
sum(is.na(x)) counting the
NA values. If you want the mean instead of the sum you can set
mean = TRUE.
Have a merry advent season!
