R: transposing and aggregating columns
I have this dataframe with v1 as names of categories and v2 as items. I need to aggregate v1 so fruit will appear only once, and all items in v2 will be transposed and placed in together in a single cell separated by comma. Any assistance will be appreciated :)
You can easily do it using transpose in aggregate function. dt<-aggregate(v2~v1,data=dt,fun=t) However you will have some unwanted text in the rolled up string which you can easily removed using gsub function dt$v2<-gsub("[c()]","",dt$v2))
