locs = params$locs

locs = locs[!is.na(locs$lat), ]

n = nrow(locs)

There are a total of r n locations in your view. Latitude range is r min(locs$lat) to r max(locs$lat).

You can also embed plots, for example:

data <- locs$altitude
    n = length(data)
    data <- as.numeric(data)
    if(n < 1) return("no data")
    hist(data, main = "Elevation", xlim = c(0,3600))
