Is there a table or catalog of aesthetics for ggplot2?
Below is the default_aes for each geom,
colour size linetype alpha fill weight shape width height angle hjust vjust family fontface lineheight

and the ugly code I used to hack this,
find_aes <- function(geom="point"){
tryCatch({
Geom <- getFromNamespace(paste("Geom", ggplot2:::firstUpper(geom), sep=""),
"ggplot2")
tmp <- unclass(Geom$default_aes)
tmp[is.na(tmp)] <- "yes"
data.frame(tmp, stringsAsFactors=FALSE)
}, error = function(e) {})
}
funs <- grep("^geom_", ls("package:ggplot2"),val=T)
geoms <- gsub("^geom_", "", funs)
all <- lapply(geoms, find_aes)
names(all) <- geoms
relevant <- sapply(all, function(x) !is.null(x) && nrow(x) > 0)
library(plyr)
results = do.call("rbind.fill",all)
rownames(results) <- names(relevant[relevant])
results[is.na(results)] <- "--"
options(width=9999)
capture.output(print(results), file="aes.txt")
Have a look to Aesthetic specifications's vignette, by Hadley Wickham:
This vignette summarises the various formats that grid drawing functions take. Most of this information is available scattered throughout the R documentation. This appendix brings it all together in one place.
The accepted answer details only the default aesthetics, here is how to get all of them :
Get all Geom* function
library(tidyverse)
env <- asNamespace("ggplot2")
all_Geoms <- ls(envir = env, pattern = "^Geom.+")
all_Geoms <- mget(all_Geoms, env)
Get all aesthetics
all_aes <- map(all_Geoms, ~.$aesthetics())
# change Geom* to geom_*
names(all_aes) <-
names(all_aes) %>%
substr(5,nchar(.)) %>%
tolower() %>%
paste0("geom_",.)
# remove if geom_* doesn't exist
all_aes[!names(all_aes) %in% ls(envir = env)] <- NULL
head(all_aes, 3)
#> $geom_abline
#> [1] "slope" "intercept" "colour" "size" "linetype" "alpha"
#> [7] "group"
#>
#> $geom_area
#> [1] "x" "y" "colour" "fill" "size" "linetype"
#> [7] "alpha" "group"
#>
#> $geom_bar
#> [1] "x" "y" "colour" "fill" "size" "linetype"
#> [7] "alpha" "group"
lay out in a long table
all_aes_long <- all_aes %>%
enframe("fun","aes") %>%
unchop(aes)
all_aes_long
#> # A tibble: 325 x 2
#> fun aes
#> <chr> <chr>
#> 1 geom_abline slope
#> 2 geom_abline intercept
#> 3 geom_abline colour
#> 4 geom_abline size
#> 5 geom_abline linetype
#> 6 geom_abline alpha
#> 7 geom_abline group
#> 8 geom_area x
#> 9 geom_area y
#> 10 geom_area colour
#> # ... with 315 more rows
lay out in a wide table
I suggest to use View() to visualize this one.
all_aes_wide <-
all_aes_long%>%
mutate(val = 1) %>%
spread(aes,val,fill = 0)
all_aes_wide

#> fun alpha angle colour family fill fontface geometry group height
