[R] How to use a text in an object of class character position to create a vector with the text as name

[Sarah Goslee]

In general, you use assign() to do that, but having object names
containing spaces should be avoided.

> mytext <- "Experiment name : CONTROL DB AD_1"
> mytext
[1] "Experiment name : CONTROL DB AD_1"
> mytext <- sub("Experiment name : ", "", mytext)
> mytext
[1] "CONTROL DB AD_1"
>
> assign(mytext, 1:10)
> ls()
[1] "CONTROL DB AD_1" "mytext"
> "CONTROL DB AD_1"
[1] "CONTROL DB AD_1"
>
>
> CONTROL DB AD_1
Error: unexpected symbol in "CONTROL DB"

Since you can't access your object by typing its name at the R prompt,
either with or without quotes, you've kind of got a problem. You could
use get(), but at that point why not just name your object something
that follows the R naming conventions?
