I installed jpeg package and tried to use kim<-readJPEG("kim.jpeg") to read in a jpeg file, but R gave me an error: Error in readJPEG("kim.jpeg") : unable to open kim.jpeg I already put "kim.jpeg" in Rstudio's default working directory: "E:\home work\Rstudio".

Hello, I have heard that Chrome OS is Linux based, so I am wondering if there is anyway to use R on a Google Chromebook using one of your Linux packages. If not, do you plan on making a version of R that is compatible with chromebooks or cloud based? [[alternative HTML version deleted]]

I am a very new R user. I am trying to write functons and debug functions.
