speed function is not giving the outputs in m/s (as its documentation indicates). That is maybe because internally the funtion is calculating the steps without considering the lonlat = TRUE argument. I have tried changing the CRS value, but it is the same.
speed.track_xyt <- function(x, append_na = TRUE, ...) {
stps <- suppressWarnings(steps(x))
s <- stps$sl_ / as.numeric(stps$dt_, units = "secs")
if (append_na) {
c(s, NA)
} else {
s
}
}
