次の問題があります!このコードを使用して、ggplot2 で図を作成します。
bi28 <- ggplot(Loc28, aes(patch, biovmean, shape=group,colour=group,group=id)) +
geom_errorbar(aes(ymin=biovmean- biovse,ymax=biovmean+biovse),
colour="black",width=.4,position=pd,size=.7) +
geom_point(size=5,position=pd) +
ylab(expression(paste(Log~biovolume~"[",µm^3~mL^-1,"]"))) +
xlab("Patch-Position") +
theme_bw() +
scale_colour_manual(name="Nutrient supply, Dispersal",
labels=c("Grad, High","Grad, Low", "Uniform, High", "Uniform, Low"),
values=c("black","darkgrey","black","darkgrey")) +
scale_shape_manual(name="Nutrient supply, Dispersal",
labels=c("Grad, High","Grad, Low", "Uniform, High", "Uniform, Low"),
values=c(19,19,17,17)) +
theme(axis.title.y=element_text(size=18, face="plain", colour="black",
vjust=0.3),axis.text.y=element_text(size=12,face="bold",
colour="black",angle=90,hjust=0.4)) +
theme(axis.title.x=element_text(size=18,face="plain",colour="black",
vjust=0),axis.text.x=element_text(size=12,face="bold",
colour="black")) +
theme(legend.key=element_blank())+theme(legend.position=c(0.6,0.14)) +
theme(legend.box="horizontal") +
theme(axis.ticks=element_line(colour="black",size=1),
axis.ticks.length=unit(0.3,"cm")) +
theme(panel.border=element_rect(colour="black",size=1.5)) +
theme(panel.grid.major=element_blank(),
panel.grid.minor=element_blank()) +
annotate("text",label="(a)",x=1,y=18.5,size=9)
ここで、geom_smooth の nls 関数を使用して、Grad、high (黒い円) と Grad、low (灰色の円) にのみ非線形曲線を追加したいと思います...
bi28 + geom_smooth(aes(group=1), method="nls",
formula=biovmean~a*patch^2+b*patch+c,start=list(a=.1,b=.5,c=.2),se=F,
linetype=1, colour="black")
...しかし、私はこのメッセージを受け取りました:
Warning messages:
1: In min(x) : no non-missing arguments to min; returning Inf
2: In max(x) : no non-missing arguments to max; returning -Inf
そして唯一のジグザグ曲線。両方の曲線を取得するには、geom_smooth(aes(.....)) を 2 回繰り返す必要があることを知っています。
ただし、図に曲線を合わせる方法がわかりません。
提案をお寄せいただきありがとうございます。
