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

Hello,
titletool<-read.csv("TotalCSVData.csv",header=FALSE,sep=",")
class(titletool)
[1] "data.frame"
titletool[1,1]
[1] Experiment name : CONTROL DB AD_1
t<-titletootl[1,1]
t
[1] Experiment name : CONTROL DB AD_1
class(t)
[1] "character"

now i want to create an object (vector) with the name "Experiment name :
CONTROL DB AD_1" , or even better if possible CONTROL DB AD_1

Thank you

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?

I know Sarah knows this, but just for archive completeness: backticks.

`cat or dog` <- 3

cat or dog # Error

`cat or dog` # 3

Of course, this allows such insanity as

`4` <- 15

which is somewhat peculiar.

I still second the advice to use legal R names and uses underscores
where spaces might be desired.

raw_data <- 3

etc.

Best,

So true.

And for convenience:
mytext <- gsub(" ", "_", mytext)
mytext
[1] "CONTROL_DB_AD_1"
raw_data <- 3

etc.
