I have the summary of ur.df function within urca package and I want to get it in Tex format. I obtained the summary by the following command

DF_infl <- summary(ur.df(infl, type = "none", lags = 0))

I tried to use xtable package to import the output of summary but since it is a sumurca class of object, it is not possible to use xtable command here. I was looking for ways to transform sumurca class of object to xtable.data.frame which is supported by xtable command but could not find the solution.

Error in UseMethod("xtable") : 
  no applicable method for 'xtable' applied to an object of class "sumurca"

How can I do that or export output of summary to Latex in some other way?

Thanks in advance!
