Builds the phase I Hotelling control chart.

1	cchart.T2.1(T2, m, n, p)

`T2`	The values of the T2 statistic. Shoul be a matrix.
`m`	The number of samples generated previously in data.1.
`n`	The size of each sample used previously in data.1. If they are individual obsersations, then use n = 1.
`p`	The dimension used previously in function data.1.

It builds the Hotelling T2 control chart for multivariate normal data (m samples / samples of size n > 1), used retrospective / validation analysis (phase I); the control limits are based on the F distribution.

Return a control chart.
