chunk takes a vector (or list) and returns a list of chunks
which all have lengths (approximately) equal to a specified value.
Usage
chunk(x, len = NULL, n = NULL)
Arguments
x
vector of list
len
target length of chunks
n
number of chunks
Details
If n is specified, len is ignored and chunk returns
a list of length n of "chunks" of x. Otherwise
n is calculated to break the vector into chunks which are
each approximately of length len. If both len and
n are unspecified, chunk simply returns x.
