how do use this "and" operator to combine two conditions. I am sorry as I know for many of you, this is very basic question but I am new to R and trying to learn it as early as possible.
The 'and' operator is called '&' in R. Try ?'&' to display the help page. You might also be interested in ?ifelse and ?"if"
