R Documentation

Get a temporary variable from the SciViews:TempEnv environment

Description

The function gets a variable, or an item in a list variable from SciViews:TempEnv, an environment dedicated to temporary variables.

Usage

getTemp(x, default = NULL, mode = "any", item = NULL)

Arguments

`x`	the name of the variable.
`default`	the default value to return, in case the variable or the item does not exist.
`mode`	the mode of the variable or the item (if the variable exists, but is not of correct mode, the default value is returned). Use `mode = "any"` (default value) to retrieve the variable or item whatever its mode.
`item`	if `NULL` (default), the whole variable content is retrieve, otherwise, the variable is considered as a list, and the corresponding item from that list is returned. In this case, `default` and `mode` arguments correspond to the item, not to the whole variable.

Value

The content of the variable, of the item, or the default value if the variable or item is not found in SciViews:TempEnv, or of the wrong mode.
