se is my SummarizedExperiment object. The problem is, every time I want to use a function inside the se[ ] to do the subsetting, that breaks my Rstudio (specificly, it will not react to any commands or operations for a few minutes, though you can still input). And later I found that three letter in the square bracket is enough to make this happened. Like:
# se[aaa], se[row, ], se[1,aaa], se[1aaa, 1] or anything else, and then the Rstudio died
# below is my object and some of its content, hope it may help
