[英]R Error: Discrete value supplied to continuous scale
The plotting code below gives Error: Discrete value supplied to continuous scale下面的绘图代码给出了错误:提供给连续比例的离散值
I already tried this solution mentioned by stack overflow community but none of them is working.我已经尝试过堆栈溢出社区提到的这个解决方案,但它们都不起作用。 I don't know what wrong with this code.我不知道这段代码有什么问题。

What's wrong with this code?这段代码有什么问题?
#Library Download
library(ggplot2)
library(dplyr)
library(ggthemes)
#Setting Working Directory
setwd("")
getwd()
#Main Code
data <- read.csv("Test2.csv",header=TRUE)
str(data)
xd <-factor(data$SampleID)
g <- ggplot()
g <- g + geom_bar(data= data,aes(x = xd, y = Average.of.Result,group=Element,color=Element),stat='identity',
position="dodge",
na.rm = FALSE,
show.legend = NA,
fill = rgb(0, 0, 0.8)
)+
theme_minimal(base_size = 12, base_family ="Segoe UI")+
geom_line(data=data,aes(x=xd,y=X10xDL,group=Element), size=1.25,color="blue",linetype = "dashed")+
geom_line(data=data,aes(x=xd,y=Expected.Value,group=Element), size=1.25,color="red",linetype = "dashed") +
theme_minimal(base_size = 12, base_family ="Segoe UI")
g
Any help???有什么帮助???
Your last geom_line uses the logical (aka boolean) values of Expected.Value
for y
, while the other y
variables are numeric.您的最后一个 geom_line 使用y
的Expected.Value
的逻辑(又名布尔)值,而其他y
变量是数字。 You could replace it with y = as.numeric(Expected.Value)
for that line, so that TRUE will become 1 and FALSE 0, which can be plotted on a continuous axis.您可以将该行替换为y = as.numeric(Expected.Value)
,这样 TRUE 将变为 1 和 FALSE 0,可以绘制在连续轴上。
ggplot(data = mutate(mtcars, am_logi = am == 1)) +
geom_line(aes(x = wt, y = mpg)) +
# geom_point(aes(x = wt, y = am_logi)) + # ERROR
geom_point(aes(x = wt, y = as.numeric(am_logi))) # NO ERROR
