R summarise by group sum giving NA

Question

I have a data frame like this

Observations: 2,190,835
Variables: 13
$ patientid       4489, 4489, 4489, 4489, 4489, 4489, 4489, 4489, 4489, 4489, 4489         


        

Answer 1

By default, sum does not consider NA.

Try this:

nutrient_intake <- nutrient_data %>% 
  group_by(patientid, doseday, enteral) %>% 
  summarise(
    energy_kcal_kg_d=sum(energy_kcal_kg, na.rm=T),
    protein_g_kg_d=sum(prot_g_kg, na.rm=T),
    lipids_g_kg_d=sum(lipids_g_kg, na.rm=T),
    na_total_mmol_kg_d=sum(Na_mmol_kg, na.rm=T),
    K_total_mmol_kg_d=sum(K_mmol_kg, na.rm=T),
    Ca_mg_total_kg_d=sum(Ca_mg_kg, na.rm=T),
    P_mg_kg_d=sum(P_mg_kg, na.rm=T),
    Pi_mmol_kg_d=sum(Pi_mmol_kg, na.rm=T)
  )
