You should try
summary(X["answer"], max = 12)
since X["answer"]
is not a vector like X$answer
but a one-column data frame.
Domanda
I am a beginner in R, but I am aware I should look for answers before asking a question here. I did, looked into help files, but to no avail. The problem is as follows: when I ask for a summary of subset X, the output of the two columns is as below. I wanted to have only the output for the answer, which I am able to to, but it is presented differently (see the output at the bottom). I want to have the results presented as a table, not as a list.
summary(X, max = 12)
results in:
student answer
Min. : 335 0 - Not at all likely : 35
1st Qu.: 855480 1 : 18
Median :1831962 10 - Extremely likely :9336
Mean :1519041 2 : 23
3rd Qu.:2183663 3 : 19
Max. :2607132 4 : 15
5 - Neutral : 939
6 : 235
7 : 921
8 :1844
9 :1194
option_i4x-DelftX-ET3034TUx-problem-b3d30df864ca41ffa0170e790f01a783_2_1_dummy_default: 71
Because I am only interested in the summary stats for answer, I used
summary(X$answer, max = 12)
And then I get the list below as answer.
0 - Not at all likely
35
1
18
10 - Extremely likely
9336
2
23
3
19

5 - Neutral

EDIT: I just found out that if you want to save/export, my solution below gives more useful output (as a table).
write.csv(data.frame(summary(X$answer)), "X.csv")
I played around a bit more, and with @JT85's suggestion, I found a nice solution.
data.frame(summary(X$answer))
and
data.frame(table(X$answer))
both work and give the output I want.
PS. It is a coincidence I found it so quickly after posting the question. This has been bugging me for 2 days already.
The output I get for data.frame(summary...) is as follows:
summary.A1.answer.
0 - Not at all likely 35
1 18
10 - Extremely likely 9336
2 23
3 19
4 15
5 - Neutral 939
6 235
7 921
8 1844
9 1194
