i using r , trying create dataframe containing information on environmental variables @ coordinates (x,y). currently working matrix altitude data. in form long, lat, altitude . and spatial points data frame containing x,y coordinates i have tried use extract function in form: xyalts <- extract(altvals,xypoints) however keep getting error: error in (function (classes, fdef, mtable) : unable find inherited method function ‘extract’ signature ‘"matrix", "spatialpointsdataframe"’ can suggest why not work? can extract function not used spatial point data frames?

the code this: the exception this: java.sql.sqlfeaturenotsupportedexception @ com.salesforce.phoenix.jdbc.phoenixresultset.first(phoenixresultset.java:173) if recode code use next() instead of first() you'll fine: while(resultset.next()) { //do resultset } if you're looking why though... you'll have go , ask developers of jdbc driver. positioning inside resultset requires scrollable resultset , possible feature not there.

is possible suppress kind of warning? note: not looking suppressing warnings(like @suppresswarnings("all") ), mentioned type. for intellij, put annotation on class has warnings @suppresswarnings("synchronizeonnonfinalfield") this lead me tag use suppression , trial , error lead me put on class instead of on field or synchronized statement. :-p

i can retrieve exchange rate on given date following command: =googlefinance("audusd","price","09/15/2015") however if market closed day googlefinance returns "n/a": =googlefinance("audusd","price","11/19/2015") how googlefinance me price though market closed? i used following solution based on utc time: import datetime dt nowutc = dt.datetime.utcnow() today14= nowutc.replace(hour=14, minute=25, second=0, microsecond=0) today21= nowutc.replace(hour=21, minute=5, second=0, microsecond=0) if (nowutc >= today21 or today14 >= nowutc): #go yahoo-finance , last value.... this solution based on times @ market closed: http://www.wisestockbuyer.com/2012/05/what-time-do-stock-markets-open-and-close/

i relatively new c++ , gsl. nonetheless have undertaken endeavour solve problem of fitting non-linear functions data implementations provided gsl. idea have class ( clnm ), holds data , model coefficients etc. clnm class has method cnlm::fitmodel_manu takes initial values , function pointers functions minimized, provided in fit_functions.cpp . i have minimal working example first generate data using formula , coefficients in example gsl reference manual provides ( y = exp(lambda*x)+b , {a,lambda,b}=<5.0,-0.1,1.0>). works out fine , data expected. with data cnlm object constructed. fitmodel_manu method called. the implementation works , code compiles fine (using g++ , iso c++11, g++ -std=c++0x ), cannot seem convergence ever, if provide correct parameters initial guess. iteration: 0 c0 = 1 c1 = 5 c2 = -0.1 |f(x)| = 1954.18 status = success iteration: 1 c0 = -15.513 c1 = 2170.38 c2 = 16.5136 |f(x)| = 902.806 status =...

for template engine use shorthand if condition. need check if value != null print out line if true. tried: echo "test" ($user->affiliate_id !=null) ? i have no idea write behind ?. the line $somevariable = $condition ? $valuea : $valueb equivalent to: if ( $condition ) { $somevariable = $valuea; } else { $somevariable = $valueb; } so, basically, if condition true , $somevariable take first value after ? symbol. if false , take second value (the 1 after : symbol). there's special case can not define first value , this: $somevariable = $somevalue ?: $someothervalue . it's equivalent to: if ( $somevalue ) { $somevariable = $somevalue; } else { $somevariable = $someothervalue; } so, if $somevalue evaluates true (any value different 0 evaluated true ), $somevariable catch value. otherwise, catch $someothervalue . to give example: function printgender( $gender ) { echo "the user's gender is: " ....
