ggsubplot是否适用于R 3.2.1+?

CRAN提供的ggsubplot版本与最新版本的R(例如3.1.1)不兼容,运行ggsubplot示例会返回错误

Error in layout_base(data, vars, drop = drop) : 
  At least one layer must contain all variables used for facetting

这是人们在StackOverflow问题中注意到的一个问题:

和GitHub发布:

然而,本月早些时候(2015-07-09)关闭了GitHub问题,这让我对ggsubplot与R 3.2.1 +

的合作持乐观态度

CRAN hosts version 0.3.2 of ggsubplot (released 2013-12-14)所以我使用包devtools从GitHub安装ggsubplot。

我试图运行阿富汗伤亡示例代码,但现在我遇到了一个不同的错误:

Error in get(x, envir = this, inherits = inh)(this, ...) : 
  could not find function "aesply"

我能做些什么来使这项工作?

另外,如何确认我正在使用哪个版本的ggsubplot?

我试过的代码如下:

## install.packages("devtools")

library(devtools)

dev_mode(on=T)

install_github("garrettgman/ggsubplot")

library(ggplot2)
## library(ggsubplot) - I just loaded this, right?
library(maps)
library(plyr)

# getbox by Heike Hoffman, 
# https://github.com/ggobi/paper-climate/blob/master/code/maps.r
getbox <- function (map, xlim, ylim) {
  # identify all regions involved
  small <- subset(map, (long > xlim[1]) & (long < xlim[2]) & (lat > ylim[1]) & (lat < ylim[2]))
  regions <- unique(small$region)
  small <- subset(map, region %in% regions)  

  # now shrink all nodes back to the bounding box
  small$long <- pmax(small$long, xlim[1])
  small$long <- pmin(small$long, xlim[2])
  small$lat <- pmax(small$lat, ylim[1])
  small$lat <- pmin(small$lat, ylim[2])

  # Remove slivvers
  small <- ddply(small, "group", function(df) {
    if (diff(range(df$long)) < 1e-6) return(NULL)
    if (diff(range(df$lat)) < 1e-6) return(NULL)
    df
  })

  small
}


## map layer
## adapted from map_nasa:
# https://github.com/ggobi/paper-climate/blob/master/code/maps.r

# assembling data
world <- map_data("world")

# building afghanistan layer
afghanistan <- getbox(world, c(60,75), c(28, 39))
map_afghanistan <- list(
  geom_polygon(aes(long, lat, group = group), data = afghanistan, 
               fill = "white", colour = "black", inherit.aes = FALSE, 
               show_guide = FALSE),
  scale_x_continuous("", breaks = NULL, expand = c(0.02, 0)),
  scale_y_continuous("", breaks = NULL, expand = c(0.02, 0)))


## 2d bin with bar chart subplots displaying data in each region
ggplot(casualties) +
  map_afghanistan +
  geom_subplot2d(aes(lon, lat,
                     subplot = geom_bar(aes(victim, ..count.., fill = victim))),
                 bins = c(15,12), ref = NULL, width = rel(0.8)) +
  coord_map()+
  theme(legend.position = "right")

似乎不再维护包ggsubplot

Message on CRAN (as of 2016-12-23)

  

包'ggsubplot'已从CRAN存储库中删除。

     

可以从存档中获取以前可用的版本。

     

根据维护人员garrett@rstudio.com的要求,于2016-01-11进行存档。

在GitHub上(https://github.com/garrettgman/ggsubplot),最后一次提交的日期可以追溯到2015-07-09。

在R 3.3.2下使用devtools::install_github('garrettgman/ggsubplot')从GitHub安装失败,并显示错误消息,抱怨缺少函数eval
