i am new with R i run these lines they worked perfectly when i run first time but second time this error"object not found" appeared
RNA1_seq <- read.delim("C:\\Users\\hp folio\\Desktop\\files.tsv")
dim(RNA1_seq)
This is just one case but it is happening to me mostly lines are perfectly right but object not found appears

First, it would be helpful if you provide the complete output from your console, since it will help figuring out the details of the problem.
The error you mention can only arise from dim():
> dim(non.existing.variable)
Error: object 'non.existing.variable' not found
This only occurs if the first command, where you declare the RNA1_seq variable, fails. Could it be that you moved those files to another location?
Edit: as Medhat suggests, you could find all the variables that are present in your global environment using ls(). If this does not list your variable RNA1_seq, you know that that is the problem.

Please use the formatting bar (especially the
codeoption) to present your post better. I've done it for you this time.Thank you!
What do you see when you list the objects use:
ls()haven,t got what you want to ask??
In the command line use this
ls()It shall give you the objects in your environment.its saying couldn't find function "Is()"
Can you write down (copy) how did you wrote it in your Rstudio or R environment ?
