You did not say what your doubt about R was.
PL2.rasch has some class.
> class(PL2.rasch)

Or you could look in the source code of whatever package you are usin.
Hello,
There are many packages that implement rasch models but I could only
find 2 with summary methods,
package pairwise and

See [1] and [2].
To see the source code at an R prompt
print the function code with
summary.
where is the output of
class(PL2.rasch)
R is open sour
You need to say what function in R is creating this. However, how are you

What python or R packages? And what functions from those packages were used?
Ideally you would provide a reproducible example, but even without
