  priority_201804 balance_201804 action_201804
1              99              0          text

4               0           -100          text

Above is a sample of my dataset. I want to search through each action looking for the first instance of the action "text", this will then be Week0, I then want to line up the priority's and balances of the next weeks, as Week1, Week2 etc.

Desirable output:

  unique_ref week0_priority week0_balance week0_action week1_priority week1_balance week1_action week2_priority week2_balance week2_action
1          1              3            30         text              1            60       letter              2            30         text
2          2              1           -40         text              2           -40         call              0           -20        visit
3          3              3           -50         text              0           -40       letter        No Data       No Data      No Data

Reproducible example of data:

action_201801=c('text,letter','visit','letter','call')
priority_201802=c('1','1','1','2')
balance_201802=c('60','-40','35','0')
action_201802=c('letter','text', 'call', 'visit')
priority_201803=c('2','2','3','2')
balance_201803=c('30','-40','-50','100')
action_201803=c('text','call','text','call')
priority_201804=c('99','0','0','0')
balance_201804=c('0','-20','-50','-100')

df3=as.data.frame(cbind(unique_ref,priority_201801,balance_201801,action_201801,priority_201802,balance_201802,action_201802,priority_201803,
