View AEME variables
Arguments
- group
character string to filter variables by group. Default is NULL. Options include "HYD" (hydrodynamic), "LKE" (Lake), "RAD" (Radiation), "CHM" (Chemistry), "PHS" (Phosphorus), "NIT" (Nitrogen), "CAR" (Carbon), "SIL" (Silica), "MET" (Meteorologica), "ZOO" (Zooplankton), "PHY" (Phytoplankton), "MAC" (Macrophytes), "NCS" (Non-conservative substances).
- var_aeme
character vector of exact AEME variable names to filter by (e.g., "HYD_temp", "CHM_oxy", "PHS_tp"). Default is NULL.
- name
character string to filter variables by partial match in either the variable name or descriptive text. Default is NULL.
