#' # PREPARATION #
#' # ----------- #
#'
#' # Save this example dataset to an object, so we can edit it:
#' my_data <- septic_patients
#'
#' # load the dplyr package to make data science A LOT easier
#' library(dplyr)
#'
#' # Add first isolates to our dataset:
#' my_data <- my_data %>%
#' mutate(first_isolates = first_isolate(my_data, "date", "patient_id", "bactid"))
#'
#' # -------- #
#' # ANALYSIS #
#' # -------- #
#'
#' # 1. Get the amoxicillin resistance percentages
#' # of E. coli, divided by hospital:
#'
#' my_data %>%
#' filter(bactid == "ESCCOL",
#' first_isolates == TRUE) %>%
#' group_by(hospital_id) %>%
#' summarise(n = n(),
#' amoxicillin_resistance = rsi(amox))
#'
#'
#' # 2. Get the amoxicillin/clavulanic acid resistance
#' # percentages of E. coli, trend over the years:
#'
#' my_data %>%
#' filter(bactid == guess_bactid("E. coli"),
#' first_isolates == TRUE) %>%
#' group_by(year = format(date, "%Y")) %>%
#' summarise(n = n(),
#' amoxclav_resistance = rsi(amcl, minimum = 20))
