整个组的趋势线 - R
trend line for a whole group - R
我正在尝试为所有组绘制一条趋势线,但它为每个组绘制了一条趋势线。我正在使用的相同代码我把它放在这里(带有 iris 数据集):
iris %>%
mutate(id = as.numeric(rownames(iris))) %>%
select(id, Sepal.Length, Sepal.Width, Petal.Length) %>%
reshape(., direction = "long", varying = names(.)[2:4], v.names = "valor", idvar = c("id"), timevar = "tipo", times= colnames(.[2:4])) %>%
ggplot(aes(x=id, y=valor, fill=tipo)) +
geom_area() +
geom_smooth(method = "lm")
我的数据帧的输出图像(没有 geom_smooth()
行)
我尝试添加趋势线:
geom_smooth(method = "lm")
但它为每个组添加了一条趋势线,而我只需要一条趋势线作为总数。
为每个单独的 geom 设置 aes
映射:
iris %>%
mutate(id = rownames(iris)) %>%
select(id, Sepal.Length, Sepal.Width, Petal.Length) %>%
reshape(., direction = "long", varying = names(.)[2:4], v.names = "valor", idvar = c("id"), timevar = "tipo", times= colnames(.[2:4])) %>%
mutate(id = as.numeric(id)) %>%
ggplot() +
geom_area(aes(x=id, y=valor, fill=tipo)) +
geom_smooth(aes(x=id, y=valor), method = "lm")
(我需要添加一个额外的变异来将 id
更改为数字以使您的代码正常工作)
