In stRoke: Clinical Stroke Research

MOVED Split to chunks of size n

Description

MOVED Split to chunks of size n

Usage

chunks_of_n(d, n, label = NULL, even = FALSE, pattern = NULL)

Arguments

d	data. Can be vector or data frame.
n	number of chunks
label	naming prefix for chunk names
even	boolean to set if size of chunks should be evenly distributed.
pattern	regex pattern to extract names from provided vector. If data frame, will assume first column is name.

Value

List of length n

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)
