ggplotly出错

Question

我想绘制4种处理中6种动物的平均访问率。我希望每个物种都有一条反映速率的线。当我运行此代码时：

library(plotly)
library(RColorBrewer)
library(extrafont)
library(MASS)
library(lme4)
library(reshape2)

dat<-read.table("R-1.AverageVisitationRatewithTrappingPeriod.csv",header=T,sep=",")
melt.data <- melt(dat,id = c("Site", "Treatment", "TrappingPeriod", "Rainfall"),
variable.name="Species",value.name="AverageVisitationRate", na.rm = TRUE)

melt.data$Treatment<-as.factor(melt.data$Treatment)
Treatment<-melt.data$Treatment
Species<-melt.data$Species
AverageVisitationRate<-melt.data$AverageVisitationRate
str(melt.data)
melt.data

plot<- ggplot(melt.data, aes(x = Treatment, y = AverageVisitationRate)) + 
geom_point(aes(color = Species)) + 
facet_grid(Treatment~Species, margins=FALSE,scales="free_y")+
stat_smooth(method = 'lm',aes(color = Species),se = FALSE)+
labs(list(x = "Treatment", y = "Average Visitation Rate"))+
theme(axis.title = element_text(family = "Arial", color="black", size=20),strip.background = element_blank())
ggplotly(plot)

然后产生此错误： Error in $<-.data.frame( TMP , "alpha", value = 1) : replacement has 1 row, data has 0

以下是我的数据示例：

抱歉，我不知道如何在这里编写表格。

错误是因为有太多的零？

我不得不删除lm，我认为你真的不能用当前的数据来做。数据文件只是.csv格式的数据......

library(plotly)
library(RColorBrewer)
#library(extrafont)
library(MASS)
#library(lme4)
library(reshape2)


melt.data<-data.frame(read.csv(file="C:\\TEMP\\testdata.csv"))

data.tall<- melt(melt.data, id.vars=c("Treatment"))
data.tall$variable <- as.factor(data.tall$variable)

plot1<- ggplot(data.tall, aes(x = Treatment, y = value)) + 
 geom_point(aes(colour = factor(variable))) + 
 facet_grid(Treatment~variable, margins=FALSE,scales="free_y")+
 # stat_smooth(method = 'lm',aes(color = variable),se = FALSE)+
 labs(list(x = "Treatment", y = "Average Visitation Rate"))+
 theme(axis.title = element_text(family = "Arial", color="black", 
   size=20),strip.background = element_blank())
  ggplotly(plot1)
