i want plot 2 time series on same graph, using xyplot. here example of mean using ts.plot() a1 = ts(rnorm(20), start=c(1980,1), freq=4) a2 = a1+3 ts.plot(a1,a2) i have tried xyplot(merge(a1,a2)) which returns error, , have tried xyplot(merge(as.xts(a1),as.xts(a2))) which plots them in different panels, not on same panel. you can combine 2 time series objects using cbind (or, alternatively, ts.union ). set superpose argument in xyplot true : xyplot(cbind(a1, a2), superpose = true) short clarification: there s3 method xyplot handles ts (time series) objects. method ( xyplot.ts ) gets called when x argument xyplot time series object.

i have table in mysql; i trying cc_rowid 10 , cc_type in on row 10 query; $stmt = $mysqli->prepare("select max(cc_rowid),max(cc_type) clock_clockings cc_eeno =(select cc_eeno clock_clockings cc_rowid=?)"); it giving me cc_rowid =10 , cc_type=out. i not understanding how improve desired results. appreciate on this. thanks if trying cc_type of max cc_rowid need like: select cc_rowid, cc_type clock_clockings cc_rowid = (select max(cc_rowid) clock_clockings); you same inner join , same subquery. 6 of one, half dozen of other. put further logic in subquery filter out else don't want in max aggregation

when connecting button in xcode @ibaction func, can choose between arguments: sender or none. when choose sender , when none? well, if action method needs know button triggered it, or can make use of of button's properties, need pass sender (the button) method. a contrived example if have calculator, has '+' , '-' button. both share action method performcalculation(sender: nsbutton ) , method use sender's symbol (this button's title ) perform correct calculation. on other hand, if have button, example clear input on textfield, wire button method clearinput() not need have information button triggered (in fact, having no argument here make easier reuse method elsewhere in code , trigger clearing textfield programmatically). i hope makes sense you. there no clear rules afaik. it's matter of taste guess.
