在r的multiplot不工作,我已經準備了多個ggplot2
圖中,保存到變量是這樣的:R:因爲錯誤UseMethod(「getModelInfo」,模型)
flashplot <- ggplot(flash, aes(x=flash$Year, y=flash$Proc))
+ stat_smooth(method="lm", formula = "flash$Proc ~ poly(flash$Year, 2, raw=TRUE)", n=14, level=0.9)
+ geom_point(shape=19) + ylab("Percentage of total existing versions")
+ xlab("Years of Existence") + scale_x_continuous(breaks = c(0,2,4,6,8,10,12,14,16,18,20))
繪製一個單一的數字作品如預期的那樣,但我想使用多點劃分4個數字(2乘2),如in the R cookbook所述。
當我得到一個錯誤,我試過的例子從食譜,我thould會的工作,但它給了我同樣的錯誤:在Windows 7下
> multiplot(p1, p2, p3, p4, cols=2)
Error in UseMethod("getModelInfo", model) :
no applicable method for 'getModelInfo' applied to an object of class "c('gg', 'ggplot')"
我,使用R 2.15.2,和ggplot2
和coefplot

任何提示,以幫助我解決我的問題將高度讚賞。我錯過了什麼嗎?我已經在網上搜索,但一無所獲有用
- 按照要求,這裏是示例數據:
library(ggplot2)
# This example uses the ChickWeight dataset, which comes with ggplot2
# First plot
p1 <-
ggplot(ChickWeight, aes(x=Time, y=weight, colour=Diet, group=Chick)) +
geom_line() +
ggtitle("Growth curve for individual chicks")
# Second plot
p2 <-
ggplot(ChickWeight, aes(x=Time, y=weight, colour=Diet)) +
geom_point(alpha=.3) +
geom_smooth(alpha=.2, size=1) +
ggtitle("Fitted growth curve per diet")
# Third plot
p3 <-
ggplot(subset(ChickWeight, Time==21), aes(x=weight, colour=Diet)) +
geom_density() +
ggtitle("Final weight, by diet")
# Fourth plot
p4 <-
ggplot(subset(ChickWeight, Time==21), aes(x=weight, fill=Diet)) +
geom_histogram(colour="black", binwidth=50) +
facet_grid(Diet ~ .) +
ggtitle("Final weight, by diet") +
theme(legend.position="none") # No legend (redundant in this graph)
multiplot(p1, p2, p3, p4, cols=2)
你能提供的數據或製造假數據,使我們有一個重複的例子,我們可以複製,粘貼和試驗? – SlowLearner
由於R食譜的例子不起作用,我認爲這對我準備好的圖不是問題。我已將食譜中的數據複製到我的問題的底部。 –
問題解決了,請參閱下面的答案。感謝你付出的努力。 –
