pull.stars(.data, var = -1)

pull.stars_proxy(.data, ...)

as.tbl_cube.stars(x, ...)

slice.stars(.data, along, index, ..., drop = length(index) == 1)

slice.stars_proxy(.data, along, index, ...)

replace_na.stars(data, replace, ...)

replace_na.stars_proxy(data, ...)

Arguments

• .data: object of class stars
• ...: see filter
• var: see pull
• x: object of class stars
• along: name or index of dimension to which the slice should be applied
• index: integer value(s) for this index
• drop: logical; drop dimensions that only have a single index?
• data: data set to work on
• replace: see replace_na : list with variable=value pairs, where value is the replacement value for NA's

Examples

tif = system.file("tif/L7_ETMs.tif", package = "stars")
x1 = read_stars(tif)
if (require(dplyr, quietly = TRUE)) {
 x1 %>% slice("band", 2:3)
 x1 %>% slice("x", 50:100)
}
