# S4 method for class 'PointFrame'
names(x)

# S4 method for class 'PointFrame'
dim(x)

# S4 method for class 'PointFrame'
length(x)

# S4 method for class 'PointFrame'
x$name

# S4 method for class 'PointFrame,ANY,ANY'
x[[i, j, ...]]

# S4 method for class 'PointFrame,missing,ANY,ANY'
x[i, j, ..., drop = TRUE]

# S4 method for class 'PointFrame,ANY,missing,ANY'
x[i, j, ..., drop = TRUE]

# S4 method for class 'PointFrame,missing,missing,ANY'
x[i, j, ..., drop = TRUE]

# S4 method for class 'PointFrame,numeric,numeric,ANY'
x[i, j, ..., drop = TRUE]

# S4 method for class 'PointFrame'
as.data.frame(x)

Arguments

data: arrow-derived table for on-disk, data.frame for in-memory representation.
meta: Zattrs
metadata: optional list of arbitrary content describing the overall object.
...: optional arguments passed to and from other methods.
x, .data: PointFrame
name: character string for extraction (see ?base::`$`).
i, j: indices for subsetting (see ?base::Extract).
drop: ignored.

Value

PointFrame
