Each of the backslashes need to be escaped with a backslash:
> ctxt <- "In Alvarez Cabral street by no. 105.\\000"
> sub("\\\\000", "", ctxt)
[1] "In Alvarez Cabral street by no. 105."

Subject: [R] Dealing with special characters at end of line in file
I am trying to fix up some image files (jpg) that have comments in them.
Unfortunately, many have had extra special characters encoded.
rdjpgcom, called from an R script, returns a comment e.g.,
"In Alvarez Cabral street by no. 105.\\000"
I want to get rid of "\\000", but sub seems
to be giving trouble.
> sub("\\000", "", ctxt)
[1] "In Alvarez Cabral street by no. 105.\\0"
Anyone know how to resolve this?
JN
