So I have two data frames.

The first one is a reccomendation data frame and the second is a melted
list with a pairing of OpportunityId's and ProductId's. There are multiple
product id's per an opportunty id. What I want to do is merge based on
ProductId so that I can add the OpportunityId to the reccomendation data
frame.
1 01t30000001ik30AAA 01ta0000005SivAAAS 01ta0000005RQimAAG
2 01t30000001ik3vAAA 01t30000001ik5bAAA 01t30000001ikKPAAY>
head(pd_melt[,1:3],2)          OpportunityId          ProductId value
4826 0063000000bqUKlAAM 01t30000001ik3vAAA     0
9651 0063000000bqUKlAAM 01t30000001ik41AAA     0





Any suggestions?

Hi

see in line
Suggestion 1 : Do not use HTML post, configure your mail client to send plain text emails
Suggestion 2 : merge(product_neighbours_orig, pd_melt, all = TRUE)

Regards
Petr
