This function creates a logical (TRUE/FALSE) sensor from specified states.

myClim object see myClim-package
The tag of states to be converted into a sensor.
A vector of names for the output sensors.
A vector of sensors containing the states to be converted into a new sensor. If NULL, states from all sensors are used. (default is NULL)
A logical value. If TRUE, the sensor value is FALSE for state intervals (default is FALSE).
Returns a myClim object in the same format as the input, with added sensors.
The function allows you to create a TRUE/FALSE sensor based on a tag. By default,
it generates a new sensor by combining all tags specified in the tag
parameter
from all available sensors at a particular logger or locality. If you specify a
source_sensor
, the function converts only the tags from that specific sensor.
You can also create multiple new sensors from multiple tags by specifying more
values in to_sensor
and providing exactly the same number of corresponding values
in source_sensor
. For example, you can create one TRUE/FALSE sensor from states
on a temperature sensor and another from tags on a moisture sensor.
If you use parameter inverse = TRUE
you get FALSE for each record where tag is assigned to and
FALSE for the records where tag is absent. By default you get TRUE for all the records
where tag is assigned.
