Description
Generate a range of integers for each row of the input columns
Usage
pl$int_ranges(start = 0, end = NULL, step = 1, ..., dtype = pl\$Int64)
Arguments
start
|
Start of the range (inclusive). Defaults to 0. |
end
|
End of the range (exclusive). If NULL (default), the value
of start is used and start is set to 0.
|
step
|
Step size of the range. |
…
|
These dots are for future extensions and must be empty. |
dtype
|
Data type of the range. |
Value
A polars expression
Examples
library("polars")
df <- pl$DataFrame(start = c(1, -1), end = c(3, 2))
df$with_columns(int_range = pl$int_ranges("start", "end"))
