Hello,
See if this is it:
priceStore_Grps$StoreID <- paste("Store",
seq_len(nrow(priceStore_Grps)), sep = "_")
Hope this helps,

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 .
# 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
