| String collection speed tests | |
| ======================================================== | |
| Source for this document at https://gist.github.com/wch/9233873 | |
| What's the fastest way to collect strings together in R and put them into a single output string? Probably the fastest way is to simply use `paste0('string1', 'string2')`, and so on -- but this assumes that you have all the strings collected and ready at one time. In many cases, this isn't possible, and you need to collect the strings together as you go. | |
| This document contains benchmarks for different ways of collecting strings together. Some highlights: | |
| * `textConnection` is super slow. |
