traits_to_csr_df: Add CSR functional group classifications to a dataframe of phytoplankton species, based on surface to volume ratio and
maximum linear dimension ranges proposed by Reynolds et al. 1988;2006
Description
Add CSR functional group classifications to a dataframe of phytoplankton species, based on surface to volume ratio and
maximum linear dimension ranges proposed by Reynolds et al. 1988;2006
a character string with one of 5 return values: C,CR,S,SR, or R
Arguments
df
name of dataframe
sav
character string with name of column that contains surface to volume ratio values
msv
character string with name of column that contains maximum linear dimension * surface to volume ratio values
msv.source
character string with reference source for distinguishing criteria
traitrange
data frame with trait criteria for c,s,r groups. The included table
can be replaced with user-defined criteria if desired. Measurements are:
Surface area/volume ratio (sav), maximum linear dimension (mld) and mld*sav (msv).
