n

number of chunks

Examples

tail(chunks_of_n(seq_len(100),7),3)
tail(chunks_of_n(seq_len(100),7,even=TRUE),3)
ds <- data.frame(nm=paste0("Sub",
add_padding(rownames(stRoke::talos))),stRoke::talos)
head(chunks_of_n(ds,7,pattern="Sub[0-9]{3}",label="grp"),2)
## Please notice that no sorting is performed. This is on purpose to preserve
## original sorting. If sorting is intended, try something like this:
ds[order(ds$nm),] |> chunks_of_n(7,pattern="Sub[0-9]{3}",label="grp") |> 
head(2)
