similar to: Improving string concatenation

Just to clarify, primitive (C-level) generics do not support dispatch on basic classes (like character). This is for performance (no need to consider dispatch on non-objects) and for sanity (in general, redefining fundamental behaviors is dangerous). It is of course possible to define a "+" method with a signature containing a class not in the set of basic classes. On Tue, Jun 16, 2015

Hi, first time poster here. During my time using R, I have always found string concatenation to be (what I feel is) unnecessarily complicated by requiring the use of the paste() or similar commands. When searching for how to concatenate strings in R, several top search results show answers that say to write your own function or override the '+' operator. Sample code like the following

Bad choice of words I'm afraid. What I'm ultimately pushing for is a feature request. To allow string concatenation with '+' by default. Sure I can write my own string addition function (like the example I posted previously) but I use it so often that I end up putting it in every script I write. It is ultimately a matter of readability and syntactic sugar I guess. As an example, I

Yeah, I agree, paste's recycling rules are sometimes painful. This could be "fixed" with a nice

I had posted this sample code previously to demonstrate how string concatenation could be implemented

In what sense is paste complicated to use? Not in the sense of

R has a lot of surprising features and I would have thought this would be quite a way down the list. How

One of the poster's on the SO post I linked to previously suggested this but if '+' were made to be S4 compliant, then adding the ability to concat strings with '+' would be a relatively simple addition (no pun intended) to the code base I believe. With a lot of other languages supporting this kind of concatenation, this is what surprised me most when first learning R. This is

if '+' and paste don't change their behavior with respect to factors but you encourage people to use '+' instead of paste then you will run into problems with data.frame columns because many people don't notice whether a character-like column is character or factor. With paste() this is not a problem but with '+' it is. I think it is good not to make people worry

Dear R gurus How do I do simple string concatenation in R? For example: A = "klm" B = "jjj" How can I assign a value to C such that C == "klmjjj" is True? Thank you Arie [[alternative HTML version deleted]]

I have this typical problem of joining a number of vectors with similar names - a1, a2,..., a10 - which should be concatenated into one. Using c(a1,a2,a3,a4,a5,a6,a,a8,a9,a10) naturally works, but I would like to do it with less manual input. My attempts to use paste() gives a vector of the vector names, see below. The question is how to do the the concatenation? Any suggestions?

When splitting long strings over multiple lines, we can use string literal concatenation instead of +.

Hi all, I have spent some time searching, but I haven't found a way to prevent * from concatenating two frames into one IAX packet. I have a situation where I make an IAX GSM call to *, which transcodes to an iLBC SIP call. Every second voice packet the IAX client receives contains 2x 20ms frames, the other containing only one. I presume this is related to the mismatch of 20ms GSM vs

Hi, Is it possible to convert a zfs pool from a concatenation of 2 disks to a 2 way mirror without backing up the data, re-creating the pool and restoring it. i.e diskA,diskB ----> mirror(diskA,diskB) Thanks, Jeff

"c" an extremely commonly-used function. Functions are first-class objects that occupy the same namespaces that variables do, so they can obscure each other. In short, don't use variables called "c" (R is case sensitive, so "C" has no such problem). Wherever possible, avoid incremental concatenation like the plague. If you feel you must use it, at least
