Function to list elements that are lists

lets say I have a list in r that contains other lists and I want to remove certain characters (comma in the following example) from elements of each list. 

my.list <- list(c("hello , world ", "hello world,,," ),c("123,456", "1,234"))

The following gets the job done

gsub(",", "", my.list[[1]])

gsub(",", "", my.list[[2]])

but how do I do it more efficiently as my actual problem is long? I tried the following but it gives me strange results

lapply(my.list, function(x) gsub(",","",my.list))

any help? thx

You might be able to utilize the function filter_element

I would suggest sanitizing your data before combining them into a list. Once the data has been sanitized, then start setting entering them into lists.

You can check out the documentation for filter_element on page 10 in the following PDF.
