string concatenation operator (revisited)
FWIW {stringi} has %+% for this functionality (and I occasionally use
it), tho I do enough processing of quite ughly string content that I
pretty much always have {stringi} loaded. That may not be true for
many other folks.

While I'm tempted to push back on some points, I don't think it's worth on balance, or will add much beyond what's already been said. It's interesting to see that there appears to be at least some appetite for additional (f)string operators in base R... notwithstanding the valid objections and the difficulties raised in this thread.

This would essentially provide a shortcut to `paste0`, in much the same way that `\(x)` now provides a shortcut to `function(x)`. a = "hello "; b = "world" a + b [1] "hello world" I appreciate some of the original concerns raised against a native "string1 + string2" implementation. The above thread also provides several use-at-your-own-risk workarounds. But sixteen years is a long time in software development and R now stands as something of an exception on this score. Python, Julia, Stata, and SQL (among various others) all support native string concatenation/interpolation using binary/arithmetic operators. It's been a surprising source of frustration for students in some of the classes I teach, particularly those coming from another language. Many thanks for considering. PS. I hope I didn't miss any additional discussion of this issue beyond the original 2005 thread. My search efforts didn't turn anything else up, except this popular Stackoverflow question: https://stackoverflow.com/questions/4730551/making-a-string-concatenation-operator-in-r Grant McDermott Assistant Professor Department of Economics University of Oregon www.grantmcdermott.com [[alternative HTML version deleted]] ______________________________________________ R-devel at r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
