Preprocessing

We can prepare necessary columns (time diffs, speeds, distances) with a single function.

colnames(obj$data)
#> [1] "timestamp"  "rotation_x" "rotation_y" "fps"        "input"     
#> [6] "position_x" "position_z" "position_y"
obj <- prepare_navr(obj)
colnames(obj$data)
#>  [1] "timestamp"        "rotation_x"       "rotation_y"      
#>  [4] "fps"              "input"            "position_x"      
#>  [7] "position_z"       "position_y"       "time_since_start"
#> [10] "time_diff"        "distance"         "distance_total"  
#> [13] "speed"            "rotation_x_diff"  "rotation_y_diff"

Removing too large speeds/teleports

#this function picks unreal speeds
i_speeds <- pick_unreal_speeds(obj, 3, "std")

#this function removes given speed AND distance measurements and recalculates total distance
obj <- remove_unreal_speeds(obj, indices = i_speeds, total_recalculate = T)
