Exporting large lists in R as .txt or .csv

Question

I have a question regarding this Text particular problem, where the question is answered, but only partially. Namely, getting the output using cat(capture.output(print(my.list), file="test.txt")) works for some elements of the list, but for longer ones does not give a full file, but rather it says [ reached getOption("max.print") -- omitted 299 entries ] and so on. Does anyone know of an alternative to exporting a list in R that does not have a limit in the no. of rows/columns? I tried all of the offered solutions in the example from the link, non of the worked. Important to mention is that I do not want to use unlist or cbind, because the groups within the list are important to stay the way they are.

Thanks!
