The version of ggsubplot available from CRAN is incompatible with recent versions of R (e.g 3.1.1), and running the ggsubplot examples returns an error about
Error in layout_base(data, vars, drop = drop) :
At least one layer must contain all variables used for facetting
It's a problem people have noted in StackOverflow questions:
and GitHub issues:
- https://github.com/garrettgman/ggsubplot/issues/14 https://github.com/garrettgman/ggsubplot/issues/10
However, the GitHub issues were closed earlier this month (2015-07-09), which made me optimistic that ggsubplot would would work with R 3.2.1+
CRAN hosts version 0.3.2 of ggsubplot (released 2013-12-14) so I used package devtools
to install ggsubplot from GitHub.
I tried to run the Afghanistan casualties example code, but I'm getting a different error now:
Error in get(x, envir = this, inherits = inh)(this, ...) :
could not find function "aesply"
Is there something I can do to make this work?
Also, how do I confirm which version of ggsubplot I'm using?
The code I tried follows:
## 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)) +
