Question

I have x = 1,2,3,4 which is my categorical variable
but when I use summary() it automatically thinks that this is discrete : so I would get something like this

Min :
1st Qu.:
Median :

But what I want is to give me just the frequency for this variable within the summary()

Answer 1

> x <- seq(1:10)

> summary(as.factor(x))
 1  2  3  4  5  6  7  8  9 10 
 1  1  1  1  1  1  1  1  1  1

Or, if you want to permanently assign x as categorical variable in a dataframe named mydata, do this before the summary() call:

mydata$x <- factor(mydata$x) 

(Spending an hour or two with any of the many books or online intros to R and typing out the examples is a smart investment and saves a lot of time.)
