如何使用R从NetCDF（360天日历）转换时间变量？

Question

我有NetCDF数据，这是摘要：

 3 dimensions:
    X  Size:83
        standard_name: longitude
        pointwidth: 0.0500000007450581
        gridtype: 0
        units: degree_east
    T  Size:356
        standard_name: time
        long_name: Time
        pointwidth: 1
        expires: 1569888000
        calendar: 360
        gridtype: 0
        units: months since 1960-01-01
    Y  Size:68
        standard_name: latitude
        pointwidth: 0.0499999970197678
        gridtype: 0
        units: degree_north

我尝试使用以下方法转换时间变量：

     nctime <- nc.get.time.series(ncin, v = "precipitation",
                           time.dim.name = "T")

并收到此错误

     > nctime <- nc.get.time.series(ncin, v = "precipitation",
         +                                time.dim.name = "T")
       Error in if (f$dim$time$len == 0) { : argument is of length zero

有什么办法可以解决这个问题吗？
