P值转化为Padj

把计算出来的储存成一个数组，然后调用函数计算，
一定是所有p值（要计算的p值集合，不能单独只计算一个p值），因为p.adj简单来说就是再p基础上再筛选出新的p值。

 p=c(0.01,0.005,0.003,0.010,0.1,0.03,0.0010,0.003,0.05,0.09)
> p
 [1] 0.010 0.005 0.003 0.010 0.100 0.030 0.001 0.003 0.050 0.090
> P.adj=p.adjust(p,method = "fdr") #这里method可以选择："holm", "hochberg", "hommel", "bonferroni", "BH", "BY","fdr", "none" 等
> round(P.adj,digits =3)
 [1] 0.017 0.012 0.010 0.017 0.100 0.043 0.010 0.010 0.062 0.100
