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 -- Shane ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
