Question

我正在关注如何使用以下link的geom_lollipop包中ggalt的教程。

我尝试运行的代码如下：

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

我的输出不是创建一个棒棒糖图，而是如下：

geom_lollipop似乎无效。此外，当我尝试数字geom_lollipop时，Rstudio似乎没有在可用的函数中找到它。

我认为这是包版本的问题，但我更新了R并重新安装了上面的所有包。遵循R和版本的使用版本：

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

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

知道为什么这不起作用吗？

Answer 1

（从评论更新）

使用ggalt_0.3.0.9000 scales_0.4.0 ggplot2_2.1.0为我工作。

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

devtools::install_github("hrbrmstr/ggalt")

并重新加载包。

geom_lollipop（包Ggalt）无效
