In order to preprocess the data, you can use the following code to extract the selected item name:<\/p>\n

 <\/p>\n

total$selecteditem <- total$options_left
\ntotal$selecteditem[total$selected== 1] <- total$options_right[total$selected== 1]<\/p><\/blockquote>\n

 <\/p>\n

To generate a 7 point likert scale from the data set, use this code<\/p>\n

 <\/p>\n

total$tracker.likert1<- total$tracker1.likert1
\ntotal$tracker.likert1[total$id==“tracker2″]<- total$tracker2.likert1[total$id==“tracker2″]
\ntotal$tracker.likert1[total$id==“tracker3″]<- total$tracker3.likert1[total$id==“tracker3″]
\ntotal$tracker.likert1[total$id==“tracker4″]<- total$tracker4.likert1[total$id==“tracker4″]
\ntotal$tracker.likert1[total$id==“tracker5″]<- total$tracker5.likert1[total$id==“tracker5″]
\ntotal$tracker.likert1[total$id==“tracker6″]<- total$tracker6.likert1[total$id==“tracker6″]
\ntotal$tracker.likert1[total$id==“tracker7″]<- total$tracker7.likert1[total$id==“tracker7″]<\/p><\/blockquote>\n

In both instances, we use the data frame total<\/strong> and 7 different trackers.<\/p>\n

To mark the deselected item on the consideration page, use<\/p>\n

total$dropitem<-0
\ntotal$dropitem[total$item.consideration==total$selecteditem] <- 1<\/p><\/blockquote>\n

To export the code for stata\/spss, it is helpful to use<\/p>\n

write.csv2(total,“total.csv“, row.names = FALSE)<\/p><\/blockquote>\n

If you prefer decimal commas, use write.csv instead of write.csv2.<\/p>\n
