utm_zone_lookup not found

[Karine-Pigeon]

Error in lookup_epsg_code(zone, datum) :
object 'utm_zone_lookup' not found

Fixed by calling the .csv directly using utm_zone_lookup <- read.csv("https://raw.githubusercontent.com/bcgov/bcmaps/main/data-raw/utm-zone-lookup.csv")

• seems like the link needs to be updated in the function?

R version 4.3.1.
bcmaps version 2.2.0

#test Data with multiple zones, and a column denoting the zone
df <- data.frame(
animalid = c("a", "b", "c"),
zone = c(10, 11, 11),
easting = c(500000, 800000, 700000),
northing = c(5000000, 3000000, 1000000)
)
utm_convert(df, easting = "easting", northing = "northing", zone = "zone")

Hey @Karine-Pigeon can you provide some info on how you are generating this error? What function are you calling?

Also what versions of bcdata and R are you using? The output of sessionInfo() would be ideal.

Thanks for adding the reprex @Karine-Pigeon. I cannot seem to reproduce the error with bcmaps::utm_convert()—can you confirm this code errors for you in a fresh session?
