Hi,
Searching the archives has brought no clue:
For a tex chunk in an Sweave text
"Oracle query results: differences \Sexpr{varname},..."
I need to change the string varname from "X_1" to "X\_1",
sub("_",??,"X_+") -> "X\_1"
so that subsequent Latex will generate "X_1" (i.e. show the underscore)
instead of "X subscript 1" (subscripting the "1")
Various trials with sub("_","\\_",varname) and the like have not helped.
sub("_","\\_","X_1") -> "X_1"
sub("_","\\_","X_1",fixed=TRUE) -> "X\\_1"
sub("_","\_","X_1",fixed=TRUE) -> "X_1"
Latex will translate "X\\_1" to X (linefeed) 1 !!
Thanks for help
Christian
