The specified SparkDataFrame is attached to the R search path. This means that the SparkDataFrame is searched by R when evaluating a variable, so columns in the SparkDataFrame can be accessed by simply giving their names.

Usage

# S4 method for SparkDataFrame
attach(
  what,
  pos = 2L,
  name = paste(deparse(substitute(what), backtick = FALSE), collapse = " "),
  warn.conflicts = TRUE
)

Arguments

what

pos

(integer) Specify position in search() where to attach.

name

warn.conflicts

(logical) If TRUE, warnings are printed about conflicts from attaching the database, unless that SparkDataFrame contains an object

Examples

if (FALSE) {
attach(irisDf)
