i've been using @findby while now, , love fact element doesn't located until necessary (not on instantiation). however, webpage may have anywhere 2-10 of element, , id's on elements numbered (so first element has id of "element1" , forth) i write function can pass in integer, , return webelement appropriate id, and lazily instantiated. means having function following won't work: public webelement getelement(int numonpage){ return driver.findelement(by.id("element"+numonpage)); } because instant call function webelement gets located. (the reason why can't instantiated because have function waits until element exists calling isdisplayed() on , on over it, catching nosuchelementexception s). i realize create list<webelement> selects via css every element id starts "element" have had other cases i've wanted return dynamically generated element, , had use workaround there well. thanks! first, don&#

on thread on crossvalidated, made following comment: i suspect r question difference between working s3 classes (that accessed via $ ) & s4 classes (that accessed via @ )... @gavin simpson subsequently commented: @gung more spot on, solution not delve objects , rip out whatever feel learn use extractor functions, in case coefficients() or shorter alias coef() , in coef(fit) i'm intrigued this. why using coef(model) be better than model$coefficients[,1] , example? (i recognize latter uglier , requires more typing, doubt that's reason intended.) case there isn't existing extractor function (e.g., accessing t-statistics)? because author of package using free change underlying structure of model object without worrying breaking everyone's code. obviously generalizes r core well. recommended use extractor functions because can sure return correct information, if function authors find necessary shuffle things aro
