: Why doesn't R have one, like . in Perl or juxtaposition in awk?
You could define one like this:
R %+% - function(x,y) paste(x,y,sep=)
R abc %+% def
[1] abcdef

R-help@stat.math.ethz.ch mailing list
Can we do something to make the following work:
+.character - function(x,y) paste(x,y,sep=)
abc+def
Error in abc + def : non-numeric argument to binary operator
Thanks,

I believe not, because:
get(+)
.Primitive(+)
i.e., it's not an S3 generic.

You mean `imply'? In fact + *is* S3 generic and has methods defined:
methods(+)
[1] +.Date +.POSIXt
It is also group-generic, part of the Ops group with many more
