Re: [R] save and load user modifications of options
Thanks David! I got a solution, though maybe not optimal. In the zzz.r file
of the R package, I include the folloing code:
.onLoad <- function(libname,pkgname) {
myoptions <- list(ngs.python="sage -python",ngs.macs="macs14")
if(exists("myoptions",.GlobalEnv))
options(.GlobalEnv$myoptions)
else
options(myoptions)
}
If user save his options in the myoptions list, by loading saved image he
does not need to set the option again. However, I still believe there is a
more elegant way to let user save his options. Hope someone could come up
with a better solution :-)
Thanks!

[R] save and load user modifications of options
Hi, Could anyone help me with the following problem? After I finished a R session and modified some options (for example, set options(editor="neditor")), I want save these modifications so that after I load the saved R data I do not need to modify these options again. What is the best way to do this? Is there a way without using an external file? I tried save.image. However, only default setting is perserved. Thanks for your help!
