Binning Issues

[Steve Ahlswede]

I see that someone else in the discussion is having a similar problem with bins as I...I am getting the error in creating bins due to my data set having some NA values. Now I have seen your solution from someone else who had similar problems by using seq() to set up the bins but I need bins of varying lengths and as far as I know I can only make uniform lengths using seq()? If anyone knows how I can set up a sequence for my bins which incorporates varying lengths that would be fantastic! 

Thanks

How to generate fits with uneven bin widths:

library(Distance)
data(minke)
# cutmink <- create.bins(minke, cutpoints=c(0, 2,5,15))   # fail because of NAs
normal.mink <- ds(minke)
my.mink <- ds(minke, cutpoints=c(0, .2, .5, 1, 2))
par(mfrow=c(1,2))
plot(normal.mink, main="Default cutpoints")
plot(my.mink, main="Bespoke (uneven) cutpoints")

Hope that is useful.
