Try to fix non-valid PTModule objects in order to meet with
ProTracker specs such that they pass validity tests.
Usage
# S4 method for PTModule,logical
fix.PTModule(mod, verbose = T)
# S4 method for PTModule,missing
fix.PTModule(mod)Value
Returns a copy of object mod in which all non-conformaties are
attempted to be fixed. (Attempted) fixes are listed printed
in the progress report.
Details
Almost any file can be read as a PTModule object (using
read.module) when validity is ignored and no unexpected end
of file is reached. This package's object validity are very strickly testing
for compliance with ProTracker specifications. As many modules could have
been created with other trackers (which often will play just as well in
ProTracker) it is desirable to convert such object to ProTracker specs.
This method attempts to do so, by fixing each aspect, that is also tested
in the object validity functions. Note that the attempts are no guarantee for success,
and `fixed' modules may not play as intended.
Note
In the current version, pattern data itself is not checked for non-conformaties nor is it fixed.

Examples
if (FALSE) {
data("mod.intro")
## Let's do something illegal and destroy mod.intro:
mod.intro@pattern.order <- mod.intro@pattern.order[1:9]
## We should have used the 'patternOrder'-method to
## change the pattern order. Now we have broken the
## object:
validObject(mod.intro, TRUE)
## No worries, we can fix it:
mod.intro <- fix.PTModule(mod.intro)
## See, it's all OK again:
validObject(mod.intro, TRUE)
}
