Help in persp (VERY URGENT ASSISTANCE)

 
Dear All,
 
I am very new to R projects.May be i am wrong in some steps.I have given the code which i tried for drawing 3d surface using persp.I need to label the axes with scales
 
 z <- array(topnew2$V2, dim=c(600,2))
 x <- 10 * (1:nrow(z))
 y <- (1:ncol(z))
 persp(x, y, z, theta = 30, phi = 30, expand = 0.5, col = "lightblue", xlab ="fluidlevel", ylab ="time", zlab = "probability",xlim=range(x),ylim=range(y))

 
 
I have a text file  of format:
 
     V1 V2   V3
1     1  0   10
2     1  0   20
3     1  0   30
4     1  0   40
5     1  0   50
..................
 now i converted to matrix as "z" 
 
  z:............
        [,1] [,2]
  [1,]    0    0
  [2,]    0    0
  [3,]    0    0
  [4,]    0    0
  [5,]    0    0
  [6,]    0    0
  [7,]    0    0
  [8,]    0    0
...................
 
 
 
i need to label x axis with scale from 10 to 6000 with length of 10
and y axis with 1 and 2 
and z from 0 to 1(probabilty)
 
 
kindly guide me...(may be i have misunderstood some concepts in commands)...
 
thanks in advance for the help and patience
