I'm trying to figure out how to rename groups in a data frame after groups
by selected variabels. I am using the dplyr library to group my data by 3
variables as follows
# group by lat (StoreX)/long (StoreY)
priceStore <- LapTopSales[,c(4,5,15,16)]
priceStore <- priceStore[complete.cases(priceStore), ] # keep only non NA
records
priceStore_Grps <- priceStore %>%
group_by(StorePC, StoreX, StoreY) %>%
summarize(meanPrice=(mean(RetailPrice)))
which results in .
> priceStore_Grps
# A tibble: 15 x 4
# Groups: StorePC, StoreX [?]
StorePC StoreX StoreY meanPrice
<fct> <int> <int> <dbl>
1 CR7 8LE 532714 168302 472.
2 E2 0RY 535652 182961 520.
3 E7 8NW 541428 184515 467.
4 KT2 5AU 517917 170243 522.
5 N17 6QA 533788 189994 523.
Which is fine, but I then want to give each group (e.g. CR7 8LE 532714
168302) a unique identifier (say) Store 1, 2, 3 or some other unique
identifier.
StorePC StoreX StoreY meanPrice
<fct> <int> <int> <dbl>
1 CR7 8LE 532714 168302 472. Store 1
2 E2 0RY 535652 182961 520. Store 2
3 E7 8NW 541428 184515 467. Store 3
4 KT2 5AU 517917 170243 522. Store 4
5 N17 6QA 533788 189994 523. Store 5
