Hello!
Am trying to remove the “” from the result column and replace with NA and the is.na function not producing the desired output - am I using the wrong one here?
- please note - just posting for practice, this was a previous error that I have now resolved.
# load packages
pacman::p_load(rio, here, skimr, lubridate, janitor, datapasta, epikit, flextable, reprex, tidyverse)
# data
error_data <- data.frame(
stringsAsFactors = FALSE,
case_id = c(1L, 2L, 4L, 5L, 6L),
date_of_result = c("2013-03-04","2013-03-10",NA,"2013-05-15",
"2013-04-26"),
result = c("Death", "Death", "", "Recovered", "Death")
)
# change "" to NA
error_data <- error_data %>%
mutate(result, is.na(result, ""))
#> Error in `mutate()`:
#> ℹ In argument: `is.na(result, "")`.
#> Caused by error in `is.na()`:

Hello,
You will need to assign result a new value with an equals sign in the mutate() function, below I used the if_else() function to convert result to NA as you require:
# loading packages
library(tidyverse)
# creating fake data
error_data <- data.frame(
stringsAsFactors = FALSE,
case_id = c(1L, 2L, 4L, 5L, 6L),
date_of_result = c("2013-03-04", "2013-03-10", NA_character_, "2013-05-15",
"2013-04-26"),
result = c("Death", "Death", "", "Recovered", "Death")
)
# cleaning the data
clean_error_data <- error_data |>
mutate(result = if_else(result == "", NA_character_, result))
