Hi,
I think you made a copy/paste error in the documentation of the who2007.ref

Hi, Thank you for making such a wonderful package. I wonder if it is possible to add my own reference tables into the package so that I can draw a growth chart that fit my smaller population?
I currently have a set of tables containing age, sex, mean, standard deviation, percentile values a 5,25,50,75,90.

Thanks a lot

How to set up the correction for preterm infants when calculating SDS or percentile? It seems that we can use the kro.ref. Can you provide a example code? Or shall we set the age of preterm infants as negative values?

The percent BMI code appears to be bugged and is outputting a data.frame.

See attached images:

thank you for this package, especially the update. sds() is so FAST now!!

Hi
Whenever I run the sds(.) with ref = ukwho and item ='bmi' I get a series 8 of identical warnings "In regularize.values(x, y, ties, missing(ties), na.rm = na.rm) :
collapsing to unique 'x' values"

It does however produce a value which looks credible.
I am not getting this message with height or weight or with other references (such as uk1990)

Any ideas? Should the results still be reliable despite the warnings

thanks and best wishes
Phil
