manual_reorder | R Documentation |

This is a function that allows the user to manully reorder Czekanowski's Diagram and recalculates all the factors.

manual_reorder(x, v_neworder, ...)

`x` |
a matrix with class czek_matrix, czek_matrix_dist or data matrix/data.frame or dist object. |

`v_neworder` |
a numeric vector with the new ordering. |

`...` |
specifies further parameters that will be passed to the czek_matrix function. |

The function returns a Czekanowski's Diagram with the new order and recalculated factors.

# Set data #### x<-mtcars # Calculate Czekanowski's diagram czkm<-czek_matrix(x) czkm_dist<-czek_matrix(x,as_dist=TRUE) # new ordering neworder<-attr(czkm,"order") neworder[1:2]<-neworder[2:1] # reorder the diagram #if the output was Czekanowski's diagram without the distances #remembered, then the original data has to be passed so that #factors can be recalculated. new_czkm<-manual_reorder(czkm,v_neworder=neworder,orig_data=x) new_czkm_dist<-manual_reorder(czkm_dist,v_neworder=neworder) #we can also pass the original data directly new_czkm<-manual_reorder(x,v_neworder=neworder) #and this is equivalent to calling czkm<-czek_matrix(x,order=neworder) #up to the value of the "criterion_value" attribute #which in the second case can be lost, as no information is passed #on which one was originally used, while in the first case it might #be impossible to recalculate-only criteria values from seriate are supported #if a user has a custom seriation function, then they need to recalculate this #value themselves
