描述----------Description----------
function performing the core of PREDA analysis
正常执行的核心普雷达分析
用法----------Usage----------
PREDA_main(inputDataForPREDA, outputGenomicAnnotationsForPREDA
=NULL, nperms = 10000, verbose = TRUE, parallelComputations =
FALSE, multTestCorrection = "fdr", permutePerChromosome = FALSE,
blocksize = 10, permuteStatisticSign = FALSE, smoothMethod =
"lokern_scaledBandwidth_repeated", force = FALSE,
lokern_scaledBandwidthFactor = 2, limit.analysis = NULL)
参数----------Arguments----------
参数：inputDataForPREDA
A Data for PREDA object
普雷达对象的一个数据
参数：outputGenomicAnnotationsForPREDA
A GenomicAnnotationsForPREDA object. If NULL, GenomicsAnnotations for output data are obtained from inputDataForPREDA
一个GenomicAnnotationsForPREDA对象。如果为NULL，输出数据GenomicsAnnotations的从inputDataForPREDA获得
参数：nperms
Number of permutations performed in PREDA analysis.
数普雷达分析进行排列。
参数：verbose
Logical, if TRUE some messages are printed concenrning the advancement of the analysis.
逻辑的一些消息，如果属实打印concenrning分析的进步。
参数：parallelComputations
Logical, if TRUE Rmpi is used to spawn slave processes, thus using parallel computing to speedup the analysis.
逻辑，如果真Rmpi用于产卵从进程，从而加速分析的并行计算。
参数：multTestCorrection
Multiple testing correction that will be adopted to correct the statistic p-values. Possible values are "fdr", for benjamini and Hochberg multiple testing correction and "qvalue" for p-values correction performed with qvalue package.
多次测试修正，将会采取什么措施来纠正统计p值。可能的值是“FDR”，为benjamini和Hochberg多个测试校正和与qvalue包执行的P-值校正的“qvalue”。
参数：permutePerChromosome
Logical, if TRUE data parmutations are perfored separatedly for each chromsoome. In most cases the default value (FALSE) is preferable to avoid biases related to specific chromosomes extreme alterations.
逻辑，如果每个chromsoome separatedly parmutations真实数据perfored的。在大多数情况下的默认值（false）是最好避免与特定染色体的极端改变的偏见。
参数：blocksize
A parameter used to tune parallel computations if parallelComputations is TRUE. This is actually the number of permutations performed on each slave process before every communication with master process. This is useftul to reduce the numebr of network communications when slow communicatinos are established among slave processes.
一个参数用来调整并行计算如果parallelComputations为TRUE。这实际上是对每一个主进程通信之前，每个奴隶的过程中执行的排列数。这是useftul缓慢communicatinos从进程之间建立，以减少网络通信numebr的。
参数：permuteStatisticSign
Logical, if TRUE statistics signs are permuted instead of permuting data along chromsomal position.
逻辑，如果数据真实迹象的置换沿chromsomal位置的数据，而不是置换。
参数：smoothMethod
The deafault smoothing metod used in the PREDA_main function is lokern smoothing with scaled bandwidth, using a scaling factor equal to 2. Possible values are "lokern", for standard lokern smoothing, "quantsmooth", "spline" and "runningmean.x", where x is a user defined value for the number of adjacent data points using for running mean smoothing.
deafault平滑梅托德在PREDA_main功能使用是lokern平滑缩放的带宽，使用比例因子等于2。可能的值是“lokern”为标准lokern平滑，“quantsmooth”，“曲线”和“runningmean.x”，其中x是一个用户定义的值使用运行平均平滑相邻数据点的数量。
参数：force
Logical, if TRUE force skipping quantsmooth control on number of data points. Singe quantsmooth is very slow with a high number of inpuit data, a check stopping computation with more than 2000 data points in one or more chromosome was introduced. This aprameter allow skippin this security check.
逻辑，如果真力跳绳quantsmooth控制数据点的数量。烧毛quantsmooth是非常缓慢的inpuit数据，检查停止在一个或多个染色体与超过2000个数据点的计算进行了介绍。这aprameter允许skippin此安全检查。
参数：lokern_scaledBandwidthFactor
Factor of scaling for lokern estimated bandwidths
lokern估计带宽比例因子
参数：limit.analysis
Vector (numeric or character representing analyses names) to limit the output of preda analysis to a subset of input analyses.
矢量（数字或字符代表分析名称）限制普雷达分析输出，输入分析中的一个子集。

If outputGenomicAnnotationsForPREDA is NULL, a PREDADataAndResults object is returned. Otherwise a PREDAResults object is returned instead
如果outputGenomicAnnotationsForPREDA是NULL，PREDADataAndResults的对象被返回。否则PREDAResults对象，而不是返回
