Can you discuss a scenario where you used the collapse argument in the paste() function? What was the requirement and how did you achieve it?

  • None of the above
  • When you want to concatenate a vector of numbers into a single string
  • When you want to concatenate a vector of strings into a single string with a specified separator between each element
  • When you want to concatenate strings without a separator
A scenario where you might use the 'collapse' argument in the 'paste()' function is when you want to concatenate a vector of strings into a single string with a specified separator between each element. The 'collapse' argument is used to specify the separator. For example, 'paste(c("Hello", "world!"), collapse = " ")' would return "Hello world!".
