Hi Eric,
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))
}
