R读数据stringsAsFactors=F，存数据时row.names = F

stringsAsFactors=F

 

以前在r里读数据，经常把character读成factor，还得费半天劲把它转回来，尤其是把factor转成numeric还没有那么直接。例如：

dat<-read.csv("D:/chengjun/digg/digg_votes_threshold_ForOnStageTimeAnalysis.csv", 

              header=T, stringsAsFactors = F)

 

 

存数据时，经常多出一列id，很讨厌，设置row.names = F，比如：

write.csv(dat, "D:/chengjun/digg/digg_votes_threshold_ForOnStageTimeAnalysis.csv", row.names = F)
