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, Michael

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
