我正在关注如何使用geom_lollipop的教程,来自包ggalt,下面的。geom_lollipop(包Ggalt)不能正常工作

我试图运行的代码如下:

df <- read.csv(text="category,pct 
Other,0.09 
       South Asian/South Asian Americans,0.12 
       Interngenerational/Generational,0.21 
       S Asian/Asian Americans,0.25 
       Muslim Observance,0.29 
       Africa/Pan Africa/African Americans,0.34 
       Gender Equity,0.34 
       Disability Advocacy,0.49 
       European/European Americans,0.52 
       Veteran,0.54 
       Pacific Islander/Pacific Islander Americans,0.59 
       Non-Traditional Students,0.61 
       Religious Equity,0.64 
       Caribbean/Caribbean Americans,0.67 
       Latino/Latina,0.69 
       Middle Eastern Heritages and Traditions,0.73 
       Trans-racial Adoptee/Parent,0.76 
       LBGTQ/Ally,0.79 
       Mixed Race,0.80 
       Jewish Heritage/Observance,0.85 
       International Students,0.87", stringsAsFactors=FALSE, sep=",", header=TRUE) 


library(ggplot2) 
library(scales) 
library(ggalt) 


gg <- ggplot(df, aes(y=reorder(category, pct), x=pct)) 
gg <- gg + geom_lollipop(point.colour="steelblue", point.size=3, horizontal=TRUE) 
gg <- gg + scale_x_continuous(expand=c(0,0), labels=percent, 
           breaks=seq(0, 1, by=0.2), limits=c(0, 1)) 
gg <- gg + labs(x=NULL, y=NULL, 
       title="SUNY Cortland Multicultural Alumni survey results") 
gg <- gg + theme_minimal(base_family="Arial Narrow") 
gg <- gg + theme(panel.grid.major.y=element_blank()) 
gg <- gg + theme(panel.grid.minor=element_blank()) 
gg <- gg + theme(axis.line.y=element_line(color="#2b2b2b", size=0.15)) 
gg <- gg + theme(axis.text.y=element_text(margin=margin(r=-5, l=0))) 
gg <- gg + theme(plot.margin=unit(rep(30, 4), "pt")) 
gg <- gg + theme(plot.title=element_text(face="bold")) 
gg 

而不是创建一个棒棒糖的情节,我的输出如下: lollipop

看来,geom_lollipop不工作。另外,当我尝试数字geom_lollipop时,Rstudio似乎并没有在可用函数中找到它。

我认为这是一个软件包版本的问题,但我已经更新了R并重新安装了上面的所有软件包。以下版本的R和正在使用的库:

> packageVersion("ggalt") 
[1] ‘0.1.1’ 
> packageVersion("ggplot2") 
[1] ‘2.1.0’ 
> packageVersion("scales") 
[1] ‘0.4.0’ 
> R.version 
       _

language  R       
version.string R version 3.3.1 (2016-06-21)

任何想法,为什么这不工作?

适合我'ggalt_0.3.0.9000 scales_0.4.0 ggplot2_2.1.0'(也许你需要Github/devel版本?试试'devtools :: install_github(“hrbrmstr/ggalt”)'...... –

完全相同代码(第一块)适用于我(pkg作者)。也许你也可以尝试'devtools :: install_github(“hadley/ggplot2”)' – hrbrmstr

@BenBolker是的,它似乎与开发版本一起工作!非常感谢! – thepule

(从评论更新)

对我的作品与ggalt_0.3.0.9000 scales_0.4.0 ggplot2_2.1.0

也许你需要Github/devel版本?请尝试重新启动会话/卸载ggalt,然后

devtools::install_github("hrbrmstr/ggalt") 

,并重新加载包。
