Okay, what you probably want is: seq(0.4,0.0,by=0.01*sign(0.0-0.4)) ... This can be worked into the function that I posted, but it's getting a bit tricky to make it general. What you want to do is to "walk" through the values creating a sequence between each one with the above call. in.betweens<-function(x,increment) { lenx<-length(x) newx<-x[1] for(i in 1:(lenx-1)) newx<-c(newx,seq(x[i],x[i+1],by=increment*sign(x[i+1]-x[i]))[-1]) return(zapsmall(newx)) } Jim ______________________________________________ R-help@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
