fast sampling in R -

क्या base :: sample < / Code> फ़ंक्शन?

आप आधार को नष्ट करने से थोड़ा-सा गति प्राप्त कर सकते हैं: : नमूना फ़ंक्शन कॉल: 

  & gt; X & lt; - rnorm (10000) & gt; System.time (1: 100000 में मैं) x [अनंत (नमूना (10000 एल, 10 एल, गलत, नल))) उपयोगकर्ता सिस्टम बीत चुका 2.873 0.017 2.851 & gt; System.time (1: 100000 में मैं) नमूना (एक्स, 10)) उपयोगकर्ता सिस्टम बीत गया 3.420 0.025 3.258   
 आपकी समस्या के आधार पर गति बढ़ाने के अन्य और अधिक चालाक तरीके हो सकते हैं तुम्हारा कोड। एक छोटे से बड़े नमूने के साथ कई छोटे कॉलों को बदलने के तरीके के बारे में सोचें।

qt - switch/case statement in C++ with a QString type -

-
I want to use switch-case in my program but the compiler generates an error. How can I use the switch statement with QString ? The compiler gives me this error: The expression of the switch type 'QString' is invalid My code is as follows : boolStopWord (the word QString) {bool flag = false; Switch (word) {case "the": flag = true; break ; "On" case: flag = true; break ; Case "in": flag = true; break ; Case "your": flag = true; break ; Case "near": flag = true; break ; Case "all": flag = true; break ; Case "this": flag = true; break ; } Return flag; } How do I use the switch statement with a Caststring ? You can not use the switch statement in C ++ language with integral or enum types. You can formally enter the square type of object in the switch statement, but this means that the compiler will look for a user-defined conversion to convert it to an integral or enum type.

What is a Python equivalent for Ruby's define_method , which is the dynamic generation of class methods will allow? (As can be seen in Wikipedia) Functions are first-class objects in Python and assign them The properties of a class or an example can be a way of doing the same thing as a Wikipedia example: colors = {"black": "000", "red": "F00", "green": "0f0", "yellow": "ff0", "blue": "00f", "magenta": "fff", "cyan": "0ff", "white": " FFF "} Class MyStream (ARR): Pass for Name, Code in colors.iteritems (): def _in_colour ( W code = code): return '& lt; Span style = "color:% s" & gt;% s & lt; / Span & gt; ' % (Code, self) setter (histrive, "in_" + name, _in_ color)
