Re: [Rd] Improving string concatenation

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. I

Re: [Rd] Improving string concatenation

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

[Rd] Improving string concatenation

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 s

Hi Milan, I can't reproduce your first bug in R 3.2 on Windows 8.1, and I fail to reproduce that one in R 3.1.2 as well. So that might explain why that one isn't tackled. The second bug you reported I can reproduce. Cheers Joris On Tue, Jun 16, 2015 at 9:18 PM, Milan Bouchet-Valat wrote: > Hi

Hi! I was wondering whether anybody was looking at the bugs on Bugzilla. I'm asking because I've seen bugs tackled on the mailing list quite quickly, but two fully reproducible reports I've filed on Bugzilla haven't triggered any reaction in several weeks (for the older one). FWIW, these are: - L
