How to list variables in R

Question

HI, i have a lot of variables in my R Script. Each time i need to check in the environment variables. Is there any way to show or search variables in R with any pattern or string?

Hi Swathi,

You can use ls() to list all variables that are created in the environment.

ls() can be used to fetch variables in different ways

• List all Variables 

             Use ls() to display all variables.

             

• Using a character pattern

            pat = " " is used for pattern matching such as ^, $, ., etc.

            

Hope it helps!

Thanks. It worked.

I noticed that using ls() prints variables alphabetically.  How can I get it to print in the order of their column position in the data?

Thanks in advance!
