rsp_q_ functions are quick access wrappers to commonly
requested (re)SPECIATE subsets.
rsp_q_gas()
rsp_q_other()
rsp_q_pm()
rsp_q_pm.ae6()
rsp_q_pm.ae8()
rsp_q_pm.cr1()
rsp_q_pm.simplified()rsp_q_ functions typically return a respeciate
data.frame of the requested profiles.
For example:
rsp_q_gas() returns all gaseous profiles in (re)SPECIATE
(PROFILE_TYPE == 'GAS').
rsp_q_pm returns all particulate matter (PM) profiles in (re)SPECIATE
not classified as a special PM type (PROFILE_TYPE == 'PM').
The special PM types are subsets profiles intended for special
applications, and these include rsp_q_pm.ae6 (type PM-AE6),
rsp_q_pm.ae8 (type PM-AE8), rsp_q_pm.cr1 (type
PM-CR1), and rsp_q_pm.simplified (type PM-Simplified).
rsp_q_other returns all profiles classified as other in (re)SPECIATE
(PROFILE_TYPE == 'OTHER').
