Construct data.frame from fmalloc columns — create_fmalloc_data_frame • Rfmalloc

Thin constructor wrapper around data.frame() that keeps fmalloc vectors as column payloads.

Usage

create_fmalloc_data_frame(
  ...,
  row.names = NULL,
  check.names = TRUE,
  stringsAsFactors = FALSE
)

Arguments

...: Columns to include in the frame.
row.names: Optional row names for the frame.
check.names: Whether to enforce syntactic column names.
stringsAsFactors: Deprecated: retained for compatibility.

Value

A data.frame with the provided columns.

Examples

if (FALSE) { # \dontrun{
rt <- open_fmalloc(tempfile(fileext = ".bin"))
x <- create_fmalloc_vector("integer", 3, runtime = rt)
y <- create_fmalloc_vector("character", 3, runtime = rt)
x[] <- 1:3
y[] <- c("a", "b", "c")
df <- create_fmalloc_data_frame(x = x, y = y)
cleanup_fmalloc(rt)
} # }
