R help - Jun 2013 - XYZ data

I have x, y, z data. The x, y fields dont change but Z does. How do I add a
very small number onto the end of each x, y data point.

For example:

Original (X)              Original (Y)                 Original (Z)
15                               20                              30
15                               20                              40




New (X)              New (Y)                 New (Z)
15.00001             20.000001              30
15.00002             20.000002              40

Hi,
Not sure whether there is any pattern in adding the small number.
dat1<- read.table(text="
X????????????? Y???????????????? Z
15?????????????????????????????? 20????????????????????????????? 30
15?????????????????????????????? 20????????????????????????????? 40
",sep="",header=TRUE)
dat1[,1:2]<-do.call(rbind,lapply(seq_len(nrow(dat1)),function(i)
dat1[i,1:2]+0.00001*i) )
dat1
#???????? X??????? Y? Z
#1 15.00001 20.00001 30
#2 15.00002 20.00002 40

A.K.



I have x, y, z data. The x, y fields dont change but Z does. How do I add a 
very small number onto the end of each x, y data point. 

For example: 

Original (X) ? ? ? ? ? ? ?Original (Y) ? ? ? ? ? ? ? ? Original (Z) 
15 ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? 20 ? ? ? ? ? ? ? ? ? ? ? ? ? ? ?30 
15 ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? 20 ? ? ? ? ? ? ? ? ? ? ? ? ? ? ?40 




New (X) ? ? ? ? ? ? ?New (Y) ? ? ? ? ? ? ? ? New (Z) 
15.00001 ? ? ? ? ? ? 20.000001 ? ? ? ? ? ? ?30 
15.00002 ? ? ? ? ? ? 20.000002 ? ? ? ? ? ? ?40 


Thanks

You're right. I was in a hurry and misread the question
