Check for Idd, Idf and Epw objects — is_eplus

These functions test if input is a valid object of Idd, Idf, Epw and other main classes.

is_eplus_ver(ver, strict = FALSE)

is_idd_ver(ver, strict = FALSE)

is_eplus_path(path)

is_idd(x)

is_idf(x)

is_iddobject(x)

is_idfobject(x)

is_epw(x)

Arguments

ver: A character or numeric vector with suitable numeric version strings.
strict: If FALSE, ver can be a special string "latest" which represents the latest version.
path: A path to test.
x: An object to test.

Value

A logical vector.

Details

is_eplus_ver() returns TRUE if input is a valid EnergyPlus version.

is_idd_ver() returns TRUE if input is a valid EnergyPlus IDD version.

is_eplus_path() returns TRUE if input path is a valid EnergyPlus path, i.e. a path where there is an energyplus executable and an Energy+.idd file.

is_idd() returns TRUE if input is an Idd object.

is_idf() returns TRUE if input is an Idf object.

is_iddobject() returns TRUE if input is an IddObject object.

is_idfobject() returns TRUE if input is an IdfObject object.

is_epw() returns TRUE if input is an Epw object.
