Dear Sir/ Madam,
                             I am getting the following error:


geneExp <- read.table("DV_control_FPKM.txt",header=T, sep="\t",row.names=1)
geneExp=as.matrix(as.data.frame(geneExp))
head(geneExp)
geneExp2 <- read.table("DV_introgressed_line_FPKM.txt",header=T,
sep="\t",row.names=1)
geneExp2=as.matrix(as.data.frame(geneExp))
head(geneExp2)
library(diffcoexp)
allowWGCNAThreads()
res=diffcoexp(exprs.1 = geneExp, exprs.2 = geneExp2, r.method = "spearman" )
Error in exprs.1[rownames(exprs.1) != "", ] :
  incorrect number of dimensions
