## Calculate the initial similarity matrix

### Description

Calculate the initial similarity matrix

### Usage

    SimS(
      data,
      pcRatio = 0.95,
      gamma = 0.8,
      NN.method = "KNN",
      Dis.method = "Euclidean",
      LSH.TreeNum = 30,
      LSH.Dim = 1000,
      LSH.Dis = "angular",
      neiRatio = 0.65
    )

### Arguments

`data` | gene expression matrix after genes filtering
`pcRatio` | the ratio between the variance of the
`gamma` | the ratio of the global simialrity
`NN.method` | the method of finding neighbors
`Dis.method` | the distance metric in finding neighbors
`LSH.TreeNum` | the tree number of LSH
`LSH.Dim` | the dimension in LSH
`LSH.Dis` | the distance metric in LSH
`neiRatio` | ratio of the number of selected

### Value

initial similarity matrix S

gene expression matrix after PCA processing drData

### Examples

    gfData <- GenesFilter(yan)
    SimS(gfData)
