r - Adding additional panel plots to an XY lattice plot -


i'm looking change colour of line , add additional line in xy plot 

distance<-c(1,2,3,4,5,6,7,8,9,10,11,12,13) par<-c(1,3,5,9,15,12,11,6,5,4,3,1,0.5)  function1<-function(distance,param){   abs(param[1])*distance*param[2]*exp(1)*exp(-(distance*param[2])) }  function2<-function(distance,param){ param[1]+param[2]*distance }  e<-c(0.05,0.1)  f<-c(4,0.9)  p1<-xyplot(par~distance,data=control,                 xlab="exponential model", ylab=expression("c=1"),            xlim=c(0,20),            ylim=c(0,0.1),            col = ("cornsilk3"),            grid=(true),            panel=function(x,y,...){              panel.xyplot(x,y,...)              panel.lines(x,(function1(x,1,e))))}

so i'd add additional panel line function2 paired f list of parameters , have them 2 different colours can differentiate between them.

simply add line panel.lines(x,(function2(x,f)),col="red")

note also, function1(x,1,e) should function1(x,e) think.

your sample data not in data.frame control. , you'll need adjust ylim.

and final )} should }).

html - Outlook 2010 Anchor (url/address/link) -

i'm trying link specific pdf page msoutlook'10 or msword'10, #page=... anchor particularly useful , works fine elsewhere. unfortunately when click [ctr-k] in outlook or winword, links re-formatted assuming unc path. pdf file located on shared drive. using "file:" prefix links open pdf in adobe reader (outside of browser), , "http:" open inside browser. issue seem need open in browser "file:" prefix in order anchor work. know anchors work inside browser. outlook uses windows/explorer default program (based on file extension) seems open in adobe reader neglecting anchor. is aware of solution, link specific page or bookmark of shared-pdf ms outlook and/or winword link? common references: mailermailer.com/...anchor-tags-html-emails campaignmonitor.com/...anchor-links-in-email-newsletters/ stackoverflow.com/...anchor-in-pdf-document

javascript - Why does running this loop 9 times take 100x longer than running it 8 times? -

consider code: test = function() { } t = new test(); (var = 0; < 8; i++) { result = t instanceof test; } if change number of iterations 8 9 , loop take 100 times longer complete in latest version of firefox (41.0.1). tested on 2 different pcs , magic limit 8. here jsperf test used: http://jsperf.com/instanceof-8-times-vs-9-times does have idea why might happen? seems specific instanceof . not happen if else object, example check property. note: filed bugzilla bug this. jan de mooij mozilla team has posted details in bugzilla thread . here's simplistic interpretation of highly technical answers: in i < 8 case, firefox smart enough hoist result = t instanceof test; statement out of loop (according tests, doesn't seem omit altogether). in i < 9 case, apparently doesn't optimization . why? reason not clear, related fact 9 iterations threshold above function considered "hot" enough run through jit compiler. i < 8 cas...
