[R] Antwort: Re: Antwort: Re: Re: sink(): Cannot open file

[G.Maubach at weinwolf.de]

Hi Sarah, John, Jim,
Hi All,

I have set my envrionment variable 

path <- file.path("H:", "2016", "Analysis")
setwd(dir = path)

This works well cause the file is created in that directory.

I have tried

close(zz)
unlink(zz)

and neither worked nor did it work out using them together.

I had this before when working with IBM SPSS Statistics. There was a 
workaround for the problem in SPSS.

Is there one for R?

Kind regards

Georg

Try closing the type of sink you're actually opening:


zz <- file("all.Rout", open = "wt")
sink(zz, type = "message")
try(log("a"))
sink(type = "message")
close(zz)
unlink(zz)


If you look carefully at the example in?sink, there are two close
statements, one for each stream being sent to that file.

George,
I do not know what operating system you are working with, but when I use 
sink() under windows, I need to specify a valid path which I don't see in 
your code. I might, for example specify:

sink("c:\myfile.txt")
 R code goes here
sink()
with the expectation that I would create a file myfile.txt that would 
contain the output of my R program.
