In shinybatch: Launch Tasks in Batch

Description

Convert a list of task configurations into two data.tables of global and individual features.

Usage

conf_to_dt(
  confs,
  allowed_run_info_cols = c("date_creation", "date_start", "date_end", "priority",
    "status"),
  allow_descr = TRUE,
  allowed_function_cols = c("path", "name"),
  allow_args = TRUE
)

dir_conf_to_dt(
  dir_path,
  allowed_run_info_cols = c("date_creation", "date_start", "date_end", "priority",
    "status"),
  allow_descr = TRUE,
  allowed_function_cols = c("path", "name"),
  allow_args = TRUE
)

Arguments

confs	list of list. List of conf list(s) from yaml file(s).
allowed_run_info_cols	characteror or boolean (c("date_creation", "date_start", "date_end", "priority", "status")). Run info elements to be kept.
allow_descr	boolean or character (TRUE). Either a boolean specifying whether or not to keep descr elements, or column names.
allowed_function_cols	character or boolean (c("names", "path")). Function elements to be kept.
allow_args	boolean or character (TRUE). Either a boolean specifying whether or not to keep args elements, or column names.
dir_path	character. Path to the directory with tasks.

Value

a list of two tables 'tbl_global' and 'tbl_idv':

• tbl_global contains the global features of the configurations (.$run_info and .$descriptive)

• tbl_idv contains the individual features of the configurations (.$function and .$args)

Examples

dir_conf <- paste0(tempdir(), "/conf")
dir.create(dir_conf, recursive = TRUE)

# ex fun
fun_path = system.file("ex_fun/sb_fun_ex.R", package = "shinybatch")
fun_name = "sb_fun_ex"

# create 2 confs
