Hi,
Example data:
tibble::tribble(
~Item, ~Description,
123L, "something1",
123L, "something1",
123L, "something1",
321L, "something2",
321L, "something2",
321L, "something2"
)
I am trying to graph on x axis the unique descriptions, in this case a separate bar for something1 and something2
And on y axis the count of unique items, in this case bar for both of them should be at one as they each have one item.
This may help
library(tidyverse)
data_set <- tibble::tribble(
~Item, ~Description,
123L, "something1",
123L, "something1",
123L, "something1",
321L, "something2",
321L, "something2",
321L, "something2"
)
data_set %>%
group_by(Description) %>%
summarise(dist_cnt = n_distinct(Item)) %>%
ggplot()+
aes(x = Description , y = dist_cnt) +
geom_col()
it gives me this error:
in aes, we have x = Description, but in your data set, the column name Description is mismatching.
please check your data set if you have a column " Description".
the code I pasted in the post works for me with no error.
It gives me this error when I copy paste your code with the same example data
Try to restart RStudio and delete all load objects. Im copy/paste and the code make for @melih_guven run well.
Remember activate tibble and tidyverse.
