1	cluster(x, method, height, min_size)

`x`	A list with three elements output from the x_47 function. The first element is the the data matrix with the aligned retention times and recalibrated mass. The second and third elements are the median of the ppm and retention time errors respectively. These values are calculated by Dataset.
`method`	A character string indicating what agglomeration method should be used in the hclust function.
`height`	An number specifying the height at which the tree created by the hclust function should be cut.
`min_size`	An integer value indicating the minimum number of points a cluster must have. All clusters with fewer members than min_size will be reclassified as "noise" points.
