Hi All,
my current code looks lke this:
freq_ls <- structure(list(Var1 = c("zldkkd", "aakdkdk",
"aaakdkd", "aaieiwo", "vöalsl",
"ssddkdk",
"glowowp", "vvvvlaoiw", "ruklow",
"rolsl",
"delk", "inslvnz"), Anzahl = c(1772L,
761L,
536L, 317L, 197L, 160L, 30L, 20L, 10L, 6L, 6L, 1L), Prozent = c(46.4,
19.9, 14,
8.3, 5.2, 4.2, 0.8, 0.5, 0.3, 0.2, 0.2, 0)), .Names = c("Var1",
"Anzahl",
"Prozent"), class = c("tbl_df", "data.frame"), row.names = c(NA,
-12L))
ggplot(freq_ls) +
geom_bar(aes(x = Var1,
y = Anzahl),
stat = "identity",
fill = "gray") +
theme(axis.text.x = element_text(angle = 45, hjust = 1)) +
ggtitle("Title of the Plot")
I would like to add the abolute and relative frequencies on top of the
bars. In addition I want the values printed in descending ording according
to the data.
I searched the web and found:
geom_text(stat='bin',aes(label=..count..),vjust=-1)
(Source:
http://stackoverflow.com/questions/26553526/how-to-add-frequency-count-labels-to-the-bars-in-a-bar-graph-using-ggplot2
)
but this does not work in my case. Inserting the code
ggplot(freq_ls) +
geom_bar(aes(x = Var1,
y = Anzahl),
stat = "identity",
fill = "gray") +
geom_text(stat='bin',aes(label=..count..),vjust=-1) +
theme(axis.text.x = element_text(angle = 45, hjust = 1)) +
ggtitle("Title of the Plot")
results in
`stat_bin()` using `bins = 30`. Pick better value with `binwidth`.
Warning messages:
1: In is.na(x) : is.na() applied to non-(list or vector) of type 'NULL'
2: Removed 1 rows containing missing values (geom_text).
I looked in the book Wickhan: ggplot2 but could find an answer to the
question:
- How to show number if tey are pre-calculated?
- How to sort the bars according to the sequence of values in descending
order or if - pre-ordered - in the given order?
What do I have to change in my code to do it?
Kind regards
Georg
