twilight() not found in tsimageDeploymentLines()

[FlukeAndFeather]

I get:

Error in twilight(rep(tm, each = 2), lon = lon, lat = lat, rise = rise,  : 
  could not find function "twilight"

when calling tsimageDeploymentLines(). I believe it's because twilight() is a function in the SGAT package. In the line referenced below, changing twilight to SGAT::twilight might fix it?

TwGeos/R/TwGeos.R

Line 466 in 8facef4

c.dat <- data.frame(Twilight = twilight(rep(tm, each = 2), lon = lon, lat = lat,

Reproducible example.

library(TwGeos)
tagdate <- seq(as.POSIXct("2023-08-15", tz = "UTC"), 
               as.POSIXct("2023-08-30", tz = "UTC"), 
               by = "5 secs")
taglight <- sin(seq(0, 1, length.out = length(tagdate)) * 2 * pi * 15) + 1

tagdata <- data.frame(Date = tagdate, Light = taglight)

offset <- 6
lon.calib <- 80
lat.calib <- 0
lightImage(tagdata = tagdata,
           offset = offset,     
           zlim = c(0, 2))
tsimageDeploymentLines(tagdata$Date, lon = lon.calib, lat = lat.calib,
                       offset = offset, lwd = 3, 
                       col = adjustcolor("orange", alpha.f = 0.5))
