New subject: [cl-mathstats-devel] Losing symbols on system re-load

31 May 2007


      Hi Gary,
Thanks for your quick reply!
Yes, I was doing some more poking around last night, and was able to fix the
problem by adding the following exports to the package.lisp file:
(:export
   #:data-length
   #:mean
   #:sum-of-squares
   #:variance
   #:standard-deviation
   #:skewness
   #:minimum
   #:maximum
   #:range
   #:quantile
   #:median
   #:trimmed-mean
   #:mode
   #:mode-for-continuous-data
   #:data-continuous-p
   #:smart-mode
   #:multiple-modes
   #:interquartile-range
   #:tukey-summary
   #:statistical-summary
   #:significance
   #:t-significance
   #:t-test-one-sample
   #:t-test
   #:d-test
   #:t-test-matched
   #:z-test-one-sample
   #:inner-product
   #:covariance
   #:confidence-interval
   #:confidence-interval-z
   #:confidence-interval-z-summaries
   #:confidence-interval-t
   #:confidence-interval-t-summaries
   #:confidence-interval-proportion
   #:scheffe-tests
   #:print-scheffe-table
   #:cross-product
   #:dot-product
   #:r-score
   #:difference-list
   #:sum-list
   #:chi-square-2x2-counts
   #:chi-square-2x2
   #:chi-square-rxc-counts
   #:make-contingency-table
   #:chi-square-rxc
   #:g-test
   #:find-critical-value)
(:export
   #:anova-one-way-variables
   #:anova-one-way-groups
   #:print-anova-table
   #:anova-two-way-groups
   #:make-3d-table
   #:anova-two-way-variables-unequal-cell-sizes
   #:anova-two-way-variables)
(:export
   #:scalar-matrix-multiply
   #:multiply-matrices
   #:invert-matrix
   #:matrix-norm
   #:invert-matrix-iterate
   #:transpose-matrix
   #:normalize-matrix
   #:sum-of-array-elements)
(:export
   #:reduce-matrix)
(:export
   #:pythag-df
   #:svbksb-df
   #:svdcmp-df
   #:svzero-df
   #:svd-inverse-slow-df
   #:svd-inverse-fast-df
   #:pythag-sf
   #:svbksb-sf
   #:svdcmp-sf
   #:svzero-sf
   #:svd-inverse-slow-sf
   #:svd-inverse-fast-sf
   #:singular-value-decomposition
   #:svd-zero
   #:svd-back-substitute
   #:svd-solve-linear-system
   #:svdvar
   #:svd-matrix-inverse)
Of course, whether all of these are supposed to be exported or not, I don't
know. I'm also not sure if I duplicated any.
...
This is what we call "an odd thing".
Yes, I couldn't think of a reason for it at the time.
...
So that the symbol is only exported when the file is compiled ... I  
have _no_ idea how this has ever worked. Sigh.
Almost qualifies for a bar or two of the Twilight Zone theme... :-)
Anyway, thanks for your help. I'll check back in a few days or a week for
the new source to keep my stuff in sync.
Cheers,
David

Hi David,
...
Deleting the .fas files and re-loading gets back the lost symbols.
This is what we call "an odd thing".
Looking at the list you appended and revisiting the code leads me to  
suspect that the missing symbols are mostly (entirely) from the  
define-statistic macro. Which, I now see, expands into
...
(progn (eval-when (:compile-toplevel) (export 'mean))
       (defclass mean (simple-statistic) nil)
...
So that the symbol is only exported when the file is compiled ... I  
have _no_ idea how this has ever worked. Sigh.
I'll be posting an update that corrects this shortly.
(P.S., as for the values, I decided to just remove them instead of  
added clisp to the list...)
