You can use the scale function, just use the minimum instead of the mean and 
the range instead of the standard deviation.

 Dear expert,
 
 I have a series of number that looks like this
 
 x - c(-0.005282,
 0.000314,
 0.002851,
 -2.5059217162,
 -0.007545,
 -1.0317758496,
 0.001598,
 -1.2981735068,
 0.072411)
 
 How can I normalize it in R so that the new numbers
 is ranging from 0 to 1 ?

Is the what you want:

 x
[1] -0.005282  0.000314  0.002851 -2.5059217162
-0.007545 -1.0317758496  0.001598
[8] -1.2981735068  0.072411
 (x-min(x))/(max(x) - min(x))
[1] 0.969 0.971 0.972 0.000 0.968 0.5882632
0.972 0.4819563 1.000
