Subject: 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
