row_number [dplyr] – Rank a vector. row.names – Get or set row names of data frame or matrix. rowMeans – Compute the mean of each row of a numeric data frame, matrix or array. rowMedians [robustbase] – Compute the median of each row of a numeric matrix. rowSums – Compute th...
write.table(Data, file="file.txt", row.names = FALSE, quote=FALSE)——输出,quote为FALSE去掉字符串类型的双引号,write.table(stasum, "stasum.csv",row.names = FALSE,col.name=FALSE,sep=",",append=TRUE) write.csv(data,file="foo.csv",row.names=FALSE)——写成csv格式,row.names=FALSE去掉...
write.csv(data,file="foo.csv",row.names=FALSE)——写成csv格式,row.names=FALSE去掉行号 print()——打印 save.image("./data.RData")——把原本在计算机内存中(工作空间)活动的数据转存到硬盘中。 load("./RData")——加载目录中的*.RData,把文档-词项矩阵从磁盘加载到内存中 数据查看 通用对象 ...
(1)改变scale函数参数 data <- scale(data,center = FALSE,scale = FALSE) data <- melt(data) (2)改变melt函数参数 data$name <- rownames(data) data <- melt(data,id.vars = "name") 两种方法得到的结果相同,可进行后续绘图。 7. SQLite包报错 2022.03.28 Monday Error: Table xxx exists in dat...
