I am starting with R today and I've read my data in from a .dta (STATA) file. <br /><br />I wanted to test out descriptive stat functions but I get "NA", maybe because my variables were read in as something other than numbers? Any tips would be appreciated!Caitnoreply@blogger.comtag:blogger.com,1999:blog-6710487119650146215.post-55139159440102649832012-01-07T07:49:01.382-07:002012-01-07T07:49:01.382-07:00Many thanks John, and happy new year.Many thanks John, and happy new year.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-6710487119650146215.post-78859423751687554592011-10-02T11:44:45.005-07:002011-10-02T11:44:45.005-07:00===
