rstudio

问题 I was doing data wrangling with Rstudio, and while I was doing something with a very large dataset, the process died. I restarted the computer, but ever since Rstudio has not been responsive or slow due to memory limits (currently, it's occupying 8gb of my 16gb RAM). I tried doing all the standard things I found on Stackoverflow. gc() and gc(reset=T) rm(list = ls()) .rs.restartR() Restart my computer. But when I open Rstudio, the memory usage would quickly climb and make the entire thing

问题 I am working with some special characters in Rstudio. It coverts them into plain letters. print("Safarzyńska2013") [1] "Safarzynska2013" x <- "Māori" x [1] "Maori" Is there any way to read in the exact original characters.

问题 I have code to clear the workspace: rm(list=ls()) and code to clear the console: cat("\014") Is there code to clear all plots from Rstudio? 回答1: dev.off() closes the current graphical device. This clears all of the plots for me in RStudio as long as I don't have a different graphical device open at the moment. If you do have other graphical devices open then you can use dev.list() to figure out which graphical device is RStudio's. The following should do that but I haven't tested it
