## Creating 3 subgroups of milk:
ctg<-unique(milk$description)
categories<-c(ctg[1],ctg[2],ctg[3])
milk1<-dplyr::filter(milk, milk$description==categories[1])
milk2<-dplyr::filter(milk, milk$description==categories[2])
milk3<-dplyr::filter(milk, milk$description==categories[3])
## Sample use of this function:
sales_groups(datasets=list(milk1,milk2,milk3),start="2019-04",end="2019-04",shares=TRUE)
sales_groups(datasets=list(milk1,milk2,milk3),start="2019-04",end="2019-07",
barplot=TRUE, names=categories)
