corrRect | R Documentation |
Draw rectangle(s) after the correlation matrix plotted. SUGGESTION: It's more convenient to draw rectangle(s) by using pipe operator '|>' since R 4.1.0.
corrRect( corrRes = NULL, index = NULL, name = NULL, namesMat = NULL, col = "black", lwd = 2, ... )
corrRes |
List of the |
index |
Vector, variable index of diag rect |
name |
Vector, variable name of diag rect |
namesMat |
4-length character vector or 4-columns character matrix,
represents the names of xleft, ybottom, xright, ytop correspondingly.
It needs |
col |
Color of rectangles. |
lwd |
Line width of rectangles. |
... |
Additional arguments passing to function |
corrRect
needs one of index
, name
and namesMat
inputted.
While corrRect.hclust
can get the members in each cluster
based on hierarchical clustering (hclust
).
(Invisibly) returns input parameter corrRes
,
usually list(corr, corrTrans, arg)
.
