sample

Sampling with replacement

Calling Sequence

s = sample(n,X,orient)

Arguments

n

positive integer (size of sample)

X

matrix. Samples will be extracted from this matrix.

orient

Optional parameter. Admissible values are 1, 2, 'r' or 'c'

s

vector or matrix containing sample

Description

This function gives a vector (or matrix) nx1. It contains a random sample of n extractions, with replacement, from the matrix X.

s=sample(n,X) (or s=sample(n,X,'*')) returns a vector s whose values are a random sample of n values from X, extracted with replacement, from X .

s=sample(n,X,'r') (or, equivalently, s=sample(n,X,1)) returns a matrix of type size(X,'r')xn. It contains a random sample of n rows, extracted with replacement, from the rows of X.

s=sample(n,X,'c') (or, equivalently, s=sample(n,X,2)) returns a matrix of type nxsize(X,'c'). It contains a random sample of n columns, extracted with replacement from the columns of X.

Examples

X=['a' 'dd' 'arreu'; 'ber' 'car' 'zon']
s=sample(25,X)
s=sample(25,X,'r')
s=sample(25,X,'c')
