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.
