Systematic sampling of every thin'th row of a matrix or vector. Useful for culling MCMC output or denoising a plot.
thin
thin(x, thin)
The thinned vector, matrix, or array is returned.
The array to be thinned. The first dimension is the one sampled over.
The frequency of observations to keep. With thin=10 you will keep every 10th observation.
thin=10

x <- rnorm(100) thin(x, 10) # returns a 10 vector y <- matrix(rnorm(200), ncol=2) thin(y, 10) # returns a 10 by 2 matrix
