Dear All,  

I am very new to R projects.i would like to get some help regarding the graph construction using persp. May be i am wrong in some steps.I have given the commands which i tried for drawing 3d surface using persp.I would like to label the axes using the 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 )...  

thanks in advance for the help and patience
