Jim Holtman,
Thank you for your reply.
Your script is very concise and I think it could help me.
However when I run it on my real data object (musigma.lat.m) the age range from 5-50 skips certain full years (see script below).
Am not sure why that is and no error is given.
Hoping you can help.

Thank you in advance for your time and energy.
All the best,
Daniel

My guess is that we are being affected by FAQ 7.31 (good old floating
point numbers).  The test 'age %in% 5:50' might be affected by round
off.  Something like the following might be better:

age < 5 | (abs(age - round(age)) < 0.001)

This should give TRUE for all ages that are 'close' to the year.  Take
a look at your data where you thing values might be missing and set
'options(digit=20)' to print out the full values.

YES, that does the trick.
Glad to have your help for I had no idea of the existence of FAQ 7.31 nor for that matter do I completely understand what floating point number are (but that is another story :P))
Think I am all set.
Cheers again for your time and energy.
