我正在尝试在RStudio中运行rWBclimate包。我从ROpenSci复制了以下代码并粘贴在RStudio中。但我得到错误说'不知道如何自动选择类型列表对象的比例。违约持续 错误:geom_point需要以下缺失的美学:y
gbr.dat.t <- get_ensemble_temp("GBR", "annualavg", 1900, 2100)
## Loading required package: rjson
### Subset to just the median percentile
gbr.dat.t <- subset(gbr.dat.t, gbr.dat.t$percentile == 50)
## Plot and note the past is the same for each scenario
ggplot(gbr.dat.t,aes(x=fromYear,y=data,group=scenario,colour=scenario))
+ geom_point() +
geom_path() +
theme_bw() +
xlab("Year") +
ylab("Annual Average Temperature in 20 year increments")
我也尝试以下列方式使用geom_point(stat =“identity”)但不起作用:
ggplot(gbr.dat.t,aes(x=fromYear,y=data,group=scenario,colour=scenario))
+ geom_point(stat="identity") +
geom_path() +
theme_bw() +
xlab("Year") +
ylab("Annual Average Temperature in 20 year increments")
我仍然收到相同的消息“不知道如何自动选择类型列表对象的比例。默认为连续 错误:geom_point需要以下缺失的美学:y“
此外,str(gbr.dat.t)的结果如下:
> str(gbr.dat.t)
'data.frame': 12 obs. of 6 variables:
$ scenario : chr "past" "past" "past" "past" ...
$ fromYear : int 1920 1940 1960 1980 2020 2020 2040 2040 2060 2060 ...
$ toYear : int 1939 1959 1979 1999 2039 2039 2059 2059 2079 2079 ...

寻找有用的答案。

希望这会有所帮助。我所做的只是将gbr.dat.t $数据转换为数字向量
library('rWBclimate')
library("ggplot2")
gbr.dat.t <- get_ensemble_temp("GBR", "annualavg", 1900, 2100)
## Loading required package: rjson
### Subset to just the median percentile
gbr.dat.t <- subset(gbr.dat.t, gbr.dat.t$percentile == 50)
#This is the line you were missing
gbr.dat.t$data <- unlist(gbr.dat.t$data)
## Plot and note the past is the same for each scenario
ggplot(gbr.dat.t,aes(x=fromYear,y=data,group=scenario,colour=scenario)) + geom_point() +
geom_path() +
theme_bw() +
xlab("Year") +
ylab("Annual Average Temperature in 20 year increments")
