[R] Closing binary file connections

[Sven Garbade]

Hi all,

I'm writing a function that read data from a binary file. I want to
close all opened connections, but it failed:

> showConnections()
   description        class  mode text     isopen   can read can write
3  "daten/t5_all.mea" "file" "rb" "binary" "opened" "yes"    "no"     
4  "daten/t5_all.mea" "file" "rb" "binary" "opened" "yes"    "no"     
5  "daten/t5_all.mea" "file" "rb" "binary" "opened" "yes"    "no"     
6  "daten/t5_all.mea" "file" "rb" "binary" "opened" "yes"    "no"     
7  "daten/t5_all.mea" "file" "rb" "binary" "opened" "yes"    "no"     
8  "daten/t5_all.mea" "file" "rb" "binary" "opened" "yes"    "no"     
9  "daten/t5_all.mea" "file" "rb" "binary" "opened" "yes"    "no"     
10 "daten/t5_all.mea" "file" "rb" "binary" "opened" "yes"    "no"     
11 "daten/t5_all.mea" "file" "rb" "binary" "opened" "yes"    "no"     
12 "daten/t5_all.mea" "file" "rb" "binary" "opened" "yes"    "no"     
13 "daten/t5_all.mea" "file" "rb" "binary" "opened" "yes"    "no"     
> closeAllConnections()
Error in close(set[i]) : no applicable method for "close"
In addition: Warning message: 
no sink to remove 

What does this mean?

Thanks, Sven
