### Description

If your array input file follow the format in the example, you could use this function to extract array LRR and baf. Remember to load library before hands. Save 4*[# of chr] lists, each list has N entry. N = # of individuals snp_lrr: SNP LRR intensity; snp_lrr.pos: the position of the SNPs snp_baf: the BAF of the SNPs; snp_baf.pos: the position of the SNPs

### Usage

    get_array_input(dir = character(), pattern = character(), chr = NULL,
      projname = "")

### Arguments

`dir` | A string. The directory path to the folder where store signal intensity file according to chr. Type character
`pattern` | A string. The pattern of all the intensity file. Type character
`chr` | Specify the chromosome you want to generate. Must be of int from 1-22. If not specify, this function will generate files for all chromosomes. Default NULL
`projname` | Name of the project. Type character

### Value

void

### Examples

    dir <- system.file("extdata", package="iCNV")
    pattern <- paste0('*.csv.arrayicnv$')
    get_array_input(dir,pattern,chr=22,projname='icnv.demo.')
