创建ggplot堆栈栏和趋势线 [英] creating ggplot stack bar and trend line
问题描述
我正在处理名为 df
的数据框:
Date变量价值
1/1/2012 teamA 10
1/1/2012 teamA 10
1/1/2012 teamB 10
1/1/2012 teamC 15
1/2/2012 teamA 25
1/2/2012 teamB 30
1/2 / 2012 teamC 20
第二个数据框叫做 total $ c $
日期总计
1/1/2012 50
1/2/2012 70
我正在尝试创建一个ggplot堆栈var,并在同一图形上绘制一条趋势线:
ggplot(df,aes(x = Date,y = Value,fill =(variable)))+
)geom_bar(stat =identity)+
theme_bw()+
opts(title =Team Performance)+
xlab(Date)+ ylab(Score)+
geom_smooth(data = Total,
aes(Date,Total,group = 1 ),
method =lm,size = 2,color =darkblue)
我得到这个错误:
eval(expr,envir,enclos)中的错误:object'variable'not found
当我这样做时:
ggplot(df,aes(x = Date,y = Value,fill =(variable)))+
geom_bar(stat =identity)+ theme_bw()
有效
变量
c $ c> ggplot()级联到每个图层。
这意味着 fill = variable
预计在 geom_smooth
我猜在 Total
中没有任何名为 variable
的变量。将 fill = variable
移动到 geom_bar
或者将其取消映射到 geom_smooth
with fill = NULL
。
I am working with data frame called df
:
Date variable Value
1/1/2012 teamA 10
1/1/2012 teamA 10
1/1/2012 teamB 10
1/1/2012 teamC 15
1/2/2012 teamA 25
1/2/2012 teamB 30
1/2/2012 teamC 20
And a second data frame called total
Date Total
1/1/2012 50
1/2/2012 70
I am trying to create a ggplot stack var and draw a trend line for the total on the same graph like this:
ggplot(df,aes(x=Date, y=Value, fill=(variable))) +
geom_bar(stat="identity") +
theme_bw() +
opts(title = "Team Performance") +
xlab("Date") + ylab("Score") +
geom_smooth(data=Total,
aes(Date,Total,group=1),
method="lm", size=2, color="darkblue")
I get this error:
Error in eval(expr, envir, enclos) : object 'variable' not found
When I do this by itself:
ggplot(df,aes(x=Date, y=Value, fill=(variable))) +
geom_bar(stat="identity") + theme_bw()
it works
variable
object is definitely there, any ideas, what I am doing wrong here?
Aesthetics mapped in ggplot()
cascade down to each layer.
That means that fill = variable
is expected in geom_smooth
and I'm guessing that there's nothing called variable
in Total
. Either move fill = variable
to geom_bar
or unmap it in geom_smooth
with fill = NULL
.
