wrtiteBin in conjunction with seek : the position in the file is not good when writing
...tion it is written:
? If the connection is open it is read/written from its current position.
Thank you

Here is the tiny example:
The file_test.txt before:
1234567890
1234567890
The file_test.txt after:
?AA AA7890
1234567890
The file should have been like that:
123456 AA AA1234567890
## open the file in read/write mode + binary
fname <- file.path(".","txt","file_test.txt")
con_in <- file(fname,"r+b")
# move on 2 bytes
pos <- seek(con_in,2,origin="start")
# We have to repeat the command to return the good amount of read...
