compare_struct: To compare sub-regression structures
In CorReg: Linear Regression Based on Linear Structure Between Variables

Compares two sub-regression structures, considering one of them as the "true one".

1	compare_struct(trueZ = trueZ, Zalgo = Zalgo, all = TRUE, mode = "NULL")

`trueZ`	first structure (binary adjacency matrix)
`Zalgo`	second structure (binary adjacency matrix)
`all`	(boolean) Also compute the ratio for each stat.
`mode`	how to modify the structures before comparison. mode=c("NULL","hybrid","clique","sym") It allows to compare groups instead of exact sub-regressions. Does nothing by default.

`true1`	Number of links that exist in both matrices
`false1`	Number of links that exist only in Zalgo
`false0`	Number of links that exist only in trueZ
`deltadr`	Number of sub-regressions in trueZ - Number of sub-regressions in Zalgo (i.e.: negative if too much sub-regressions in Zalgo)
`true_left`	Number of variables redundant in both matrices
`false_left`	Number of variables redundant in Zalgo but not in trueZ
`ratio_true1`	ratio of links in trueZ that exist also in Zalgo
`ratio_true0`	ratio of links not in trueZ that don't exist in Zalgo.
