vec_fill_missing
Fill in missing values with the previous or following value
Description
![[Experimental]](../help/figures/lifecycle-experimental.svg)
vec_fill_missing() fills gaps of missing values with the previous or
following non-missing value.
Usage
vec_fill_missing(
x,
direction = c("down", "up", "downup", "updown"),
max_fill = NULL
)Arguments
x |
A vector |
direction |
Direction in which to fill missing values. Must be either
|
max_fill |
A single positive integer specifying the maximum number of
sequential missing values that will be filled. If |
Examples
x <- c(NA, NA, 1, NA, NA, NA, 3, NA, NA) # Filling down replaces missing values with the previous non-missing value vec_fill_missing(x, direction = "down") # To also fill leading missing values, use `"downup"` vec_fill_missing(x, direction = "downup") # Limit the number of sequential missing values to fill with `max_fill` vec_fill_missing(x, max_fill = 1) # Data frames are filled rowwise. Rows are only considered missing # if all elements of that row are missing. y <- c(1, NA, 2, NA, NA, 3, 4, NA, 5) df <- data_frame(x = x, y = y) df vec_fill_missing(df)
