Function to pull all sensor IDs for a district — pull_sensor_ids • tc.sensors

Create a tidy dataframe containing sensor IDs for a MnDOT district, mainly to be used with pull_sensor(). Data is fetched from the Mayfly API.

pull_sensor_ids(pull_date = NULL, district = "metro", .quiet = TRUE)

Arguments

pull_date: character, the date to query for available sensors. Accepts either "YYYY-MM-DD" or "YYYYMMDD" format. If NULL (default), uses the most recent available date.
district: character, MnDOT district code. Default is "metro". Use mayfly_get_districts() to see available districts.
.quiet: logical, whether to suppress error messages. Default TRUE

Value

data.table containing variable "detector"

Examples

if (FALSE) { # \dontrun{
library(tc.sensors)
sensors <- pull_sensor_ids()
# Get sensors for a different district
sensors_d1 <- pull_sensor_ids(district = "d6")
# Get sensors for a specific date
sensors_date <- pull_sensor_ids(pull_date = "2020-01-15")
} # }
