Hi,

In R, I know the method table(), which builds a contingency table of the counts y at each level for the factor x.
But I would like to know what is the inverse method of table(), if it exists, to obtain the vector z, from the two vectors x and y?

x <- (86,  90,  94,  98, 102, 106, 110, 114, 118, 122, 126, 130, 134, 138, 142, 146, 150, 154, 158, 162, 166, 170, 174)
y <- c(2, 5, 10, 17, 26, 60, 94, 128, 137, 128, 77, 68, 65, 60, 51, 26, 17, 9, 5, 2, 3, 7, 3)

> z
   [1]  86  86  90  90  90  90  90  94  94  94  94  94  94  94  94  94  94  98  98  98  98  98  98  98  98  98  98  98  98  98  98  98  98  98 102 102 102 102 102
  [40] 102 102 102 102 102 102 102 102 102 102 102 102 102 102 102 102 102 102 102 102 102... 
  [976] ...170 170 170 170 170 170 170 174 174 174

If such a method does not exist, what code should I type to obtain the complete series quickly?

Thank you for your help.
I use version 2.10-1 2009-08-24 for Mac OS.
