Error: object 'sim' not found
I generate dataset 'sim' from a R function. As you can see from the result,
I can see the data I generated, but why the sim could not be found? As I
can not get sim, so I can not save the data as a text file. Do you know how
to save a dataset generated within a function?
Thanks |

发帖数: 346 | 6 Thank you guys. I figured out it will also work if I write table inside the
function.
x=function(n){
sim=rnorm(n)
return(sim)
write(sim,"path")
}
x(n=10) |
