报错集锦

1、列的数目比列的名字要多

分析原因：表头列数小于实际列数。如下图

修改方法：读取的时候去掉表头

> user1rotation2 <- read.csv(“G:\LabRealated\PublicDataset\CPS\data\user1\2\rotationvector.csv”,header = F)

还有一种原因说是：可能是因为文本的编码不是utf-8造成的，解决方法：添加一条fileEncoding = "utf-8"

> user1rotation2 <- read.csv(“G:\LabRealated\PublicDataset\CPS\data\user1\2\rotationvector.csv”,header = T, fileEncoding = "utf-8")

2、分割符缺失

> e1 <- read.table("dang.txt")
Error in scan(file = file, what = what, sep = sep, quote = quote, dec = dec,  : 
  line 1 did not have 44 elements
#解决办法，加上分隔符“\t”
> e2 <- read.table("SraRunTable.txt",sep = "\t")

3

> dotplot(ego_cc,title="GO CC Enrichment")
wrong orderBy parameter; set to default `orderBy = "x"`
> pdf(file="CC_dot.pdf",width=10)
> dotplot(ego_cc,title="GO CC Enrichment",orderBy = "GeneRatio")
> dev.off()
