Hello
I am an epidemiologist supporting an Ebola response. I tried to clean my date column, but all the values were converted to NA and I am not sure why. I tried looking in the Epi R handbook but could not figure it out. Any help greatly appreciated.
Reprex below:
install and load packages
pacman::p_load(rio, janitor, tidyverse, datapasta, reprex)
data
surv_raw ← data.frame(
stringsAsFactors = FALSE,
case_id = c(“694928”,“86340d”,“92d002”,“544bd1”,“6056ba”),
sex = c(“m”, “f”, “f”, “f”, “f”),
onset_date = c(“11/9/2014”,“10/30/2014”,“8/16/2014”,“8/29/2014”,“10/20/2014”)
)
try to convert column to class “Date”
surv_clean ← surv_raw %>%
clean_names() %>%
mutate(onset_date = ymd(onset_date))
check the CLEANED date column class and date range
class(surv_clean$onset_date)
range(surv_clean$onset_date)
