Examples

 d <- data.frame(x=1:10, y=rnorm(10), tms=Sys.time() + 1:10, id=gl(2, 5))
sp::coordinates(d) <- ~x+y
## this avoids complaints later, but these are not real track data (!)
sp::proj4string(d) <- sp::CRS("+proj=laea +ellps=sphere", doCheckCRSArgs = FALSE)
tr <- trip(d, c("tms", "id"))

if (require(adehabitatLT)) {
    ##l <- as.ltraj.trip(tr)
    ##ltraj2trip(l)
    ##as.trip(l)
}
