mpa(E, tmax=7, palabras=NULL)  
contar.si(x,n)
reemplazar.si(x, n, p)

`E`	The matrix of associations between the keywords.
`tmax`	Maximum size of each group.
`palabras`	Vector containing the names of each of your keywords.
`x`	Numeric vector.
`n`	Scalar.
`p`	Scalar.

mpa function executes the associated words method from the association matrix E, and the maximum group size, tmax. Function contar.si counts the number of times the scalar n appears in a vector n. The function reemplazar.si searches for values equal to n and replaces them with p in a vector x.

Function mpa creates a list with the next components:

`Clases`	A vector that identifies the group of which every key word is associated. If a value of 0 drops out means that the keyword in the particular position was not classified
`Nombres`	The vector which specifies the names of each of the groups.
`Resumen`	Matrix that contains the size, density and centrality of each group.
