刚开始接触R,程序报错，但是找不到错误，希望大神可以帮忙。

> Nox<-read.table("C:/User/lenovo/Desktop/热图.txt",header=TRUE,sep="C:\")
+ View(Nox)
+ Nox1<-Nox[,-1]
+ row.names(Nox1)<Nox$ID
+ Nox2<-data.matrix(Nox1)
+ Nox3<-log2(Nox2+0.01)
+ library(gplots)
+ heatmap.2(Nox3,Rowv=NA,Colv=NA,dendrogram=('none'),distfun=dist, hclustfun=hclust,col=colorpanel(10,low = "white", mid = "orange",high = "red"),scale = "row" ,keysize=1.5,margins=c(5,10),density.info=c('none'), trace="none",vline=NA,hline=NA,cexRow=0.8,cexCol=0.6,colsep=c(1:ncol(Nox3)),  rowsep=c(1:nrow(Nox3)),sepcolor="white",sepwidth=c(0.01, 0.01),srtCol=315,adjCol=c(0,0))

错误: unexpected symbol in:
"library(gplots)
heatmap.2(Nox3,Rowv=NA,Colv=NA,dendrogram=('none'),distfun=dist, hclustfun=hclust,col=colorpanel(10,low = "white"
需要画一个热图，但是刚开始用这个命令，不太了解，希望帮忙解答一下错误，急用，谢谢！
