Using the barlop in R studio

Question

I have an exercise that tells me to do if the lessons are more than 5.0. I must take the students who passed the lessons to do it as bar chart.

this is the Data_passed image.I want to make students and the grade bar chart

I did that barplot(table(student$d_grade)) but it says me student didn't find.

dataframe :

Data_passed <- structure(list(student = c(21118, 21118, 21118, 21118, 21118, 21118), course = c("C2", "C5", "C3", "C1", "C4", "C7"), year = c(2013, 2013, 2013, 2013, 2013, 2013), exam = c("F1", "F1", "F2", "F1", "S1", "S1"), grade = c(7, 7.5, 7.5, 5.8, 8.2, 6.5), d_grade = c("Good", "Very Good", "Very Good", "Medium", "Very Good", "Good")), row.names = c(NA, -6L), class = c("tbl_df", "tbl", "data.frame"))

Maybe you can try this

barplot(table(Data_passed[c("student", "d_grade")]))

data

Data_passed <- structure(list(student = c(21118, 21118, 21118, 21118, 21118, 21118), course = c("C2", "C5", "C3", "C1", "C4", "C7"), year = c(2013, 2013, 2013, 2013, 2013, 2013), exam = c("F1", "F1", "F2", "F1", "S1", "S1"), grade = c(7, 7.5, 7.5, 5.8, 8.2, 6.5), d_grade = c("Good", "Very Good", "Very Good", "Medium", "Very Good", "Good")), row.names = c(NA, -6L), class = c("tbl_df", "tbl", "data.frame"))

Error in df[c("student", "d_grade")] : object of type 'closure' is not subsettable – maikl May 25 '21 at 11:16
@maikl Please show your data by `dput(df)` – ThomasIsCoding May 25 '21 at 11:17
function (x, df1, df2, ncp, log = FALSE) { if (missing(ncp)) .Call(C_df, x, df1, df2, log) else .Call(C_dnf, x, df1, df2, ncp, log) } – maikl May 25 '21 at 11:18
@maikl What's the name of your data? Use `dput` and copy/paste to your post. – ThomasIsCoding May 25 '21 at 11:19

@maikl No, that's not your data. Read https://stackoverflow.com/a/5963610/12158757 – ThomasIsCoding May 25 '21 at 11:24
@maikl what's the name of your data frame? – ThomasIsCoding May 25 '21 at 11:28
Data_passed is the dataframe – maikl May 25 '21 at 11:30
@maikl then run `dput(Data_passed)`, and copy/paste the output to your post. – ThomasIsCoding May 25 '21 at 11:31
@ThomaslsCoding I do it. but it was too much so I can't put it all – maikl May 25 '21 at 11:37
@maikl We can use part of it, e.g., `dput(head(Data_passed))` – ThomasIsCoding May 25 '21 at 11:40
