I was doing topic 4 of the swirl course (programacion-estadistica-r), but when the document inmigintnalpry.csv was opened, Rstudio stopped and the system (Ubuntu 18.04) was frozen. The only way to turn it on and off is with the power button. All information is stored in ~ / .RData. Now every time I start Rstudio the whole system freezes. What I can do?
