Dear Ian,
I have rechecked my data and my code and think I have been able to solve
the problem. The error message I reported may have resulted from the
following: My code to get an array from an xy spreadsheet did also
transform my data from numerical into string, visible by quotation
marks. Because I am new to R, I first did not pay attention to this. I
have now removed the second line from the code I sent you. This line
was an (unnecessary) operation transforming my initial dataframe into a
matrix (and at the same time, for some reason which I ignore, also into
strings). Consequently, procGPA processes even my 2LM test dataset. I
am sorry for the confusion.
Best wishes,
Louis

Dear Louis,
Thanks. I'll be at a workshop next week, but hopefully I'll be able to look
at your new dataset. Do check for missing landmarks or possibly one
observation
with landmarks all the same - that is the most common type of error with
procGPA. However, it would be good to find out what the problem is so that
I can add a more helpful error message for future users.
Thanks,
Ian

Dear Ian,
I am sorry, I sent you an inappropriate dataset, since a GPA with 2
landmarks doesn´t make much sense. I had used this dummy set for writing
the transformation code. On monday, I will send you a real dataset. I
obtained the same error messag with this, too.
Best wishes,
Louis

RE: problem with procGPA
Louis,
If you send me your code and an example when it happens
I'll look at it for you.
Kind regards,
Ian Dryden

Dear colleagues,
trying to use procGPA in R on an array of landmark configurations, I
obtained the following error message:
"Error in if (d2 == 0) { : Missing value, where TRUE/FALSE is expected".
Since "d2 == 0" is contained neither in my array nor in the procGPA
command, I suspect it might by something internal to the function. Does
anybody have a clue?
Thanks for help
