#Dplyr summarize ignore na code#
However when I implement the same code in the context of the function the final row is all NA's while the preceding rows are fine. Which in the context of this MWE works fine. Mutate(mean = map(data, ~ summarise_at(.x, vars(contains("t3")),įuns(mean_expr = mean(., na.rm = TRUE) ))), This is a nice way of quickly seeing that you have missing values in your data. a value we do not know, it cannot create a correct calulcation, so it will return NA again. I have written a function to take the raw data and process my data so that it looks a like this: example % R is very clear about trying to do calculations when there is an NA. Both these lines result in error: md > groupby(device1, device2) > summariseeach(funs(mean), na.rm TRUE) md > groupby(device1, device2) > summariseeach(funs(mean, na. I am having trouble creating a MWE but here is a more specific example. I want the NAs to be ignored (na.rm TRUE) - I tried, but the function doesn't want to accept this argument. What is the correct way to implement summarise_at() when there are NA's?ĮDIT: I see that my examples do not adequately reproduce the problem. L_num_mean_meas M_num_mean_meas N_num_mean_meas The code seems to be working in someway since the grouping seems fine, however the daily sums are missing, result is NA.Given data such as this: library(tidyverse)Į % select_at(vars(contains("_num"))) %>% colMeans(na.rm = T)īut neither of these do: e %>% summarise_at(vars(contains("_num")), mean, na.rm=TRUE)Į %>% summarise_at(vars(contains("_num")), funs(mean_meas = mean(., na.rm = TRUE))) R: Combine columns ignoring NAs - Stack Overflow WebThis example demonstrates what happens when we do not actively avoid NA values when summarizing a. Returning values with size 0 or >1 was deprecated as of 1.1.0. A data frame, to add multiple columns from a single expression. The value can be: A vector of length 1, e.g. The name will be the name of the variable in the result.
nutrient_intake % group_by(patientid, doseday, enteral) %>% summarise(energy_kcal_kg_d=sum(energy_kcal_kg), protein_g_kg_d=sum(prot_g_kg), lipids_g_kg_d=sum(lipids_g_kg), na_total_mmol_kg_d=sum(Na_mmol_kg), K_total_mmol_kg_d=sum(K_mmol_kg), Ca_mg_total_kg_d=sum(Ca_mg_kg), P_mg_kg_d=sum(P_mg_kg), Pi_mmol_kg_d=sum(Pi_mmol_kg)) < data-masking > Name-value pairs of summary functions.$ Pi_mmol_kg NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, …Īnd I would need to calculate for each patient the daily sum of nutrient intakes. How individual dplyr verbs changes their behaviour when applied to grouped data frame.
