Percentile

Fill in missing values.

Fills missing values in using the previous entry. This is useful in the common output format where values are not repeated, they're recorded each time they change.

Usage
fill(data, ..., .direction = c("down", "up"))
Arguments
data

A data frame.

...

A selection of columns. If empty, all variables are selected. You can supply bare variable names, select all variables between x and z with x:z, exclude y with -y. For more options, see the dplyr::select() documentation. See also the section on selection rules below.

.direction

Direction in which to fill missing values. Currently either "down" (the default) or "up".

Details

Missing values are replaced in atomic vectors; NULLs are replaced in list.
