代码：

multiExpr=read.csv("5000.csv",header=T,comment.char = "",check.names=F)
datTraits=read.csv("Trait1.csv",row.names=1,header=T,comment.char = "",check.names=F)
allowWGCNAThreads()
ALLOW_WGCNA_THREADS=4
memory.limit(size = 20000)
# 检查数据是否正确：
exprSize = checkSets(multiExpr)
# 统计样本数量和基因数量

运行结果：

> multiExpr=read.csv("5000.csv",header=T,comment.char = "",check.names=F)
> datTraits=read.csv("Trait1.csv",row.names=1,header=T,comment.char = "",check.names=F)
> allowWGCNAThreads()
Allowing multi-threading with up to 8 threads.

读入数据后，我的基因只有5000个，上面

> memory.limit(size = 20000)
[1] 32457    这里怎么是32457

检查数据是否正确时 出现以下错误：

> exprSize = checkSets(multiExpr)
Error in checkSets(multiExpr) : 
  data does not appear to have the correct format. Consider using fixDataStructureor setting checkStructure = TRUE when calling this function.
