similar to: 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. 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

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

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

The situation for R is rather different from that of a

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

Dear all, I want to concatenate the elements of two vectors such as a<-c("a1","a2") b<-c("b1","b2") and obtain "a1b1", "a1b2","a2b1","a2b2" I tried the paste and paste0 functions, but they yielded elementwise concatenation such as "a1b1","a2b2" I am wondering that is there an efficient

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

I could do this...and I have before. This brings up a more fundamental question though. You're asking me to write code that changes the logic of the installation process (i.e. writing my own package installer). Instead of doing that, I would rather integrate that logic into R itself to improve the baseline installation process. This api proposal change would be additive and would not break

Thank you for your help in advance. I am trying to pull some data back from a web service library(httr) sample2 <- GET("https://elevation.mapzen.com/height?json={\"range\":false,\"shape\":[{\"lat\":40.7,\"lon\":-76.5}]}&api_key=mycode") result2 <- content(sample2) height <- result2$height[[1]] I would like to put by own latitude

a) you need to read the help pages on the paste function... more likely you are looking for the paste0 function because extra spaces will most likely break the GET request format. b) quotes do not become "stuck" as \" ... that is a visual representation intended to clarify that that quote is not terminating the string but is actually part of it. If you want to see the contents

I have this: <%= @tech_standard.category + " " + @tech_standard.point + "." + @tech_standard.subpoint %> I get this error: cannot convert Fixnum into String point and subpoint are number.

Hello, Currently if you install a package twice: install.packages("testit") install.packages("testit") R will build the package from source (depending on what OS you're using) twice by default. This becomes especially burdensome when people are using big packages (i.e. lots of depends) and someone has a script with: install.packages("tidyverse") ... ... later

Hi Gabe, Keeping track of where a package was installed from would be a nice feature. However it wouldn't be as reliable as comparing hashes to decide whether a package needs re-installation or not.

Maybe I wasn't clear about my query. I'm very familiar with pre-allocation and vectorization and I had already wrote an R code for this problem in this way. My question wasn't about the most efficient way to solve the problem. It was about whether in R it was possible to use the same index used in the loop to create a new variable and store the results in as in the example showed

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]]
