Subject: [Rd] filled.contour(): no check when z dimension dismatch (PR#1432)
Message-ID: <200204031251.OAA21435@pubhealth.ku.dk>

`filled.contour()' doesn't complain if z matrix dimension doesn't match
x and y arguments. It would be safer if `filled.contour()' displays an
error (or a warning) message as `contour()' does.

For example :

   > x <- 1:3
   > z <- matrix(data=1:16, nrow=4, ncol=4)
   > filled.contour(x, x, z) # z is (4x4) whereas x is (1x3).
   ## no error/warning. 

   > contour(x, x, z)
   Error in contour(as.double(x), as.double(y), z, as.double(levels), labels,  :

         dimension mismatch
