我有一个轨迹数据集，我使用两个数据集（经度和时间）来聚类一组轨迹，我先调用Traj包然后开始使用这些函数，当我应用因子分析时出现错误：< / p>

I had the following error:
> [1] "m6 is removed because it is perfectly correlated with m5"
> [2] "m8 is removed because it is perfectly correlated with m7"
> [3] "m13 is removed because it is perfectly correlated with m12"
> [1] "Computing reduced correlation e-values..."
> Error in smc(data) :
> m5 is perfectly correlated with a prevois measurment. It must be removed.m7 is perfectly correlated with a prevois measurment. It must be removed.m9 is perfectly correlated with a prevois measurment. It must be removed.m10 is perfectly correlated with a previous measurment.
