SpatioTemporal.cluster

The goal of SMI is to 对时空关联的干旱进行特征分析

Installation

安装Julia

• Install Julia (>=1.5.3)
• Install StatsBase, RCall package
• In Julia, build RCall, ensure using RCall works

安装SpatioTemporal.cluster

devtools::install_github("kongdd/SpatioTemporalCluster")

Example

推荐使用julia版本的cluster_SpatioTemporal，且设置method = "tree"，此版本下速度最快

library(SpatioTemporalCluster)
clusterIds <- cluster_SpatioTemporal_julia(arr, method = "tree",
    ncell_connected = 1L, ncell_overlap = 5L, factor = 1e4, diag = FALSE)
