[RkWard-devel] Need some clarification

[SJR]

Hi there
yesterday I changed in corr_matrix.php the line

rk.header ("Correlation Matrix", parameters=list ("Method", "<? getRK 
("method"); ?>", "Exclusion", <? echo ($use); ?>))

to

rk.header ("Correlation Matrix", parameters=list ("Method", "<? getRK 
("method"); ?>", "Exclusion", "<? getRK ("use"); ?>"))

because "use" wasn't handed over to rk.header (and I assumed this is the right 
way to do so). Now Thomas changed it back and defined use global in function 
printout () {} (which obviously makes sense). Actually I do not understand 
why THIS is the way to go. And why doesn't this apply to "method"? What do I 
oversee?
