ds.bp_standards.RdThe function calculates blood pressure z-scores in two steps: Step 1. Calculates z-score of height according to CDC growth chart (Not the WHO growth chart!). Step 2. Calculates z-score of BP according to the fourth report on BP management, USA

)the name of the sex variable. The variable should be coded as 1 for males and 2 for females. If it is coded differently (e.g. 0/1), then you can use the ds.recodeValues function to recode the categories to 1/2 before the use of ds.bp_standards
the name of the age variable in years.
the name of the height variable in cm.
the name of the blood pressure variable.
logical. If TRUE (default) the function assumes conversion of systolic blood pressure. If FALSE the function assumes conversion of diastolic blood pressure.
a character string that provides the name for the output object
that is stored on the data servers. Default name is set to bp.newobj.
a list of DSConnection-class objects obtained after login.
If the datasources argument is not specified the default set of connections will be
used: see datashield.connections_default.
assigns a new object on the server-side. The assigned object is a list with two elements: the 'Zbp' which is the zscores of the blood pressure and 'perc' which is the percentiles of the BP zscores.
