定义多盒图的X轴值

Question

嗨，我试图得到我的X轴值标记为"TDN"，"DIN"，"PN"，"TDP"，"SRP"，"PP"，"PN"，"PN.PP"，"TDN.TDP“，而不是由R.任何帮助都将不胜感激！以下是我所创造的：

par(mfrow= c (1,8), mar = c(5,4,2,1))
boxplot(WQ.flow$TDN, WQ.flow$DIN, WQ.flow$PN, WQ.flow$TDP, WQ.flow$SRP, 
WQ.flow$PP, WQ.flow$PN.PP, WQ.flow$TDN.TDP)

Answer 1

只需指定names参数，如下所示：

boxplot(WQ.flow$TDN, 
        WQ.flow$DIN,
        WQ.flow$PN,
        WQ.flow$TDP,
        WQ.flow$SRP,
        WQ.flow$PP,
        WQ.flow$PN.PP,
        WQ.flow$TDN.TDP,
        names = c("TDN", "DIN", "PN","TDP","SRP","PP","PN","PN.PP","TDN.TDP"))
