calibrate {clickableImageMap}

calibrate

Description

use coordinates of upper left and bottom right of matrix to construct mapping between viewport coordinates and matrix cells

Usage

calibrate(m, rows, pullDownRow)

Arguments

m

matrix

rows

list of row heights in the gtable object

pullDownRow

integer number of the target row in the gtable object

Value

returns a list whose components are matrices representing the upper and lower coordinates of the row and column cells

Examples

if(interactive()){
m<-matrix(1:20 * .05,nrow=2,ncol=10)
load("data/x_rows.RData")
pullDownRow<-which(names(x_rows)=="pullDownRow")
load("data/x_m.RData")
cal<-calibrate(x_m,x_rows,pullDownRow)
}
