fill

From tidyr v0.8.3 by Hadley Wickham

Fill in missing values.

Fills missing values in selected columns 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, nothing happens. You can supply bare variable names, select all variables between x and z with x:z, exclude y with -y. For more selection options, see the dplyr::select() documentation.
.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.

Examples

# NOT RUN {
df <- data.frame(Month = 1:12, Year = c(2000, rep(NA, 11)))
df %>% fill(Year)
# }
