向量的赋值与读取
数据框的操作
读取本地
read.table(file="huahua.txt",sep="\t",header=T)设置行名和列名
X<-read.csv('doudou.txt') rownames(X) colnames(X)[1]<-"bioplanet" X<-read.csv(file = "huahua.txt",sep = " ",header =T,row.names=1数据框导出
write.table(X,file = "yu.txt",sep = ",",quote=F)变量保存与加载
save.image(file="bioinfoplanet.RData") save(X,file="test.RData") load("test.RData")
代码报错的问题。。。x未正确赋值
