Use a jlview object within a scope, releasing it on exit — with_jlview • jlview

Creates a jlview object and ensures it is released when the scope exits, even if an error occurs. This prevents memory leaks from forgotten releases.

Usage

with_jlview(
  julia_array,
  expr,
  writeable = FALSE,
  names = NULL,
  dimnames = NULL
)

Arguments

julia_array: A JuliaObject referencing a Julia array
expr: An expression to evaluate with the jlview object bound to .x
writeable: Passed to jlview
names: Passed to jlview
dimnames: Passed to jlview

Value

The result of evaluating expr

Examples

if (FALSE) { # \dontrun{
JuliaCall::julia_setup()
JuliaCall::julia_command("big = randn(100000)")
result <- with_jlview(JuliaCall::julia_eval("big"), {
    c(mean(.x), sd(.x))
})
# .x is automatically released here
} # }
