Hi Sarah,

yes, I followed your suggestion.

If I do exactly what is in the example of the documentation:

sink("C:/Temp/sink-examp.txt")
i <- 1:10
outer(i, i, "*")
sink()
unlink("C:/Temp/sink-examp.txt")

it does not write anything, i. e. no file is created in "C:/Temp/". The 
script is executed without an error or warning message.

If I run

## capture all the output to a file.
zz <- file("C:/Temp/all.Rout", open = "wt")
sink(zz)
sink(zz, type = "message")
try(log("a"))
## back to the console
sink(type = "message")  # I think ,this was your suggestion
sink()
unlink("C:/Temp/all.Rout")

the script is executed without error or warning message, the file is 
created in "C:/Temp/" but if I try to open it right away after the script 
is done the message

DE: "Auf das Dokument "C:\Temp\all.Rout" kann nicht zugegriffen werden, da 
es von einer anderen Anwendung verwendet wird."
EN: "Cannot access the document "C:\Temp\all.Rout" cause it is used by 
another application."

What do I do wrong?

Kind regards

Georg

But did you do that ^^ as I suggested?


If you start a message sink with
sink(zz, type="message")
as you did, you need to explicitly close that stream. Just using
sink()
doesn't do it.
