Rstudio和R功能（）不一样吗？

Question

I have a question about R and Rstudio capabilities() .

I installed R-3.3.2 and here is the output of capabilities() in R :

 >capabilities()
       jpeg         png        tiff       tcltk         X11        aqua 
       TRUE        TRUE       FALSE       FALSE        TRUE       FALSE 
   http/ftp     sockets      libxml        fifo      cledit       iconv 
       TRUE        TRUE        TRUE        TRUE        TRUE        TRUE 
        NLS     profmem       cairo         ICU long.double     libcurl 
       TRUE       FALSE        TRUE        TRUE        TRUE        TRUE

Then I installed Rstudio1.1 , and when I run capabilities() on Rstudio , the capabilities() are not the same (for exemple for cairo) :

    >capabilities()
       jpeg         png        tiff       tcltk         X11        aqua 
       TRUE        TRUE       FALSE       FALSE        TRUE       FALSE 
   http/ftp     sockets      libxml        fifo      cledit       iconv 
       TRUE        TRUE        TRUE        TRUE        TRUE        TRUE 
        NLS     profmem       cairo         ICU long.double     libcurl 
       TRUE       FALSE       FALSE       FALSE        TRUE        TRUE

I verified if Rstudio runs the right version of R and yes it does.

I found nothing related to this kind of problem on other posts.
