Extracting portions of one vector to create others
Dear Colleagues, I have a vector which indicates membership of subjects in one of 5 Classes Beth$CLASS [1] 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 [37] 2 2 2 2 2 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 7 7 7 7 7 7 7 7 7 7 7 [73] 7 7 7 7 7 7 7 7 7 9 9 9 9 9 9 9 9 9 9 9 9 9 9 1 For purposes of an analysis (using linear models based on Ward and Jennings) I would like to create 5 new vectors The values in vector CLASS1 will be ?1? if the corresponding value in Beth$CLASS is equal to ?1?; ?0? otherwise The values in vector CLASS2 will be ?1? if the corresponding value in Beth$CLASS is equal to ?2?; ?0? otherwise The values in vector CLASS4 will be ?1? if the corresponding value in Beth$CLASS is equal to ?4?; ?0? otherwise The values in vector CLASS7 will be ?1? if the corresponding value in Beth$CLASS is equal to ?7?; ?0? otherwise The values in vector CLASS9 will be ?1? if the corresponding value in Beth$CLASS is equal to ?9?; ?0? otherwise How would I go about this using R Thank you _________________ Paul Zachos, PhD Director, Research and Evaluation Association for the Cooperative Advancement of Science and Education (ACASE) 110 Spring Street Saratoga Springs, NY 12866 | paz at acase.org | www.acase.org
