Hi everyone,

thank you everyone who has taken the time to help me before, I am really, really appreciative. Since I don't know the language that well yet and I am very much learning by doing, as I finish the project I am working on presently, I struggle with finding the errors, when I apply the answers others were given online.

I have created a stacked bar chart and I would very much like to add counts to the columns.

surveyresponses_Freizeit_Master_for_stacked %>%
  pivot_longer(-Arbeit, names_to = "Group", values_to = "value") %>%
  summarise(count = sum(value), .by = c("Arbeit", "Group")) %>%
  ggplot(aes(Group, count, fill = Arbeit,)) +
  geom_col() +
  theme(axis.text.x = element_text(angle = 60, vjust = 1, hjust=1))

This would be my code, and it produced the graph as I need it... However, when I tried to add the count, based on this code that tackled a similar problem:

library(ggplot2)

ggplot(mtcars, aes(cyl, fill = factor(gear))) +
  geom_bar(position = "fill") +
  geom_text(aes(label = after_stat(count)),
    stat = "count", position = "fill"
  )

I receive this result:

Browse[1]> surveyresponses_Freizeit_Master_for_stacked %>%
+   pivot_longer(-Arbeit, names_to = "Group", values_to = "value") %>%
+   summarise(count = sum(value), .by = c("Arbeit", "Group")) %>%
+   ggplot(aes(Group, fill = Arbeit, label = after_stat(count)), stat = "count") +
+   geom_col() +
+   theme(axis.text.x = element_text(angle = 60, vjust = 1, hjust=1))
Error during wrapup: Problem while mapping stat to aesthetics.
ℹ Error occurred in the 1st layer.
Caused by error:
! Aesthetics must be valid computed stats.
✖ The following aesthetics are invalid:
• `label = after_stat(count)`
ℹ Did you map your stat in the wrong layer?

I understand the error message, but I am not sure what I ned to change to get the desired result... Again, I appreciate any help!

Hi everyone,

I have tried finding out what the issue is for quite some time now, but since I am not the most proficient regarding technology, I am struggling finding something applicable.

My goal was to do a simple pie chart with plotly, but for some reason the code that I used previously and copy-pasted, always comes back with the 'unexpected symbol' error. I have tried finding a punctuation error or a misspelling, but nothing. I downloaded the new version of R Studio today and I think I might be missing some packages, but I also don't know which ones they might be and my research did not yield anything. I have installed tidyverse, plotly, dplyr, ggplot2 and readxl.

I used the code from this website and adjusted it for my dataset

https://www.geeksforgeeks.org/r-language/how-to-create-pie-chart-using-plotly-in-r/

'plotly::plot_ly(data=surveyresponses_Freizeit_Bachelor_count,values=~n,labels=~factor(Bleibt genug Zeit für Freizeit?),'

'marker=list(colors=c("green","orange","blue")),'
'type="pie") %>% layout(title="Bleibt genug Zeit für Freizeit im Bachelor?")'

I look forward to any input and thank you all in advance for your help. Maybe it's something really stupid, that I just didn't see...
