Question on EBImage package

I am having trouble using the "resize" function (in the package EBImage) with matrices containing double values. Let's say I have a matrix 'b' with these values:

a = c(1.25,1.555,1.245,1.265,1.656,1.235,1.848,1.959,1.548,1.245454,1.989,1.24)
b = matrix(a,4,3)
b

       [,1]  [,2]     [,3]
[1,] 1.250 1.656 1.548000
[2,] 1.555 1.235 1.245454
[3,] 1.245 1.848 1.989000
[4,] 1.265 1.959 1.240000


I then use the resize function to increase the size of the matrix to a 6 by 10 matrix, but unfortunately there is a glitch: all of the numbers come out as ones:

y = resize(b,6,10)
y

Image
   colormode: Grayscale
   storage.mode: double
   dim: 6 10
   nb.total.frames: 1
   nb.render.frames: 1
imageData(object)[1:5,1:6]:
      [,1] [,2] [,3] [,4] [,5] [,6]
[1,]    1    1    1    1    1    1
[2,]    1    1    1    1    1    1
[3,]    1    1    1    1    1    1
[4,]    1    1    1    1    1    1
[5,]    1    1    1    1    1    1

Does anyone know why this is happening? When I use integer values, the function produces correct output.
Thank you for your help.
