Question

में निरंतर गर्मी का नक्शा बनाना मेरे पास एक्स और वाई निर्देशांक की एक श्रृंखला है जिसमें प्रत्येक के पास एक दूरी है। मैं एक ताप नक्शा बनाना चाहता हूं जो एक्स और वाई के भीतर प्रत्येक बिंदु के लिए औसत दूरी को गर्मी मानचित्र के रूप में प्रदर्शित करता है। चूंकि अंक एक दूसरे से जाली-समान आकार में समान रूप से नहीं होते हैं, इसलिए विधि को कुछ प्रकार के स्मूथिंग फ़ंक्शन की आवश्यकता होती है जो क्लस्टर डेटा और प्रत्येक बिंदु के लिए औसत की गणना करता है और फिर उस रंग को औसत के साथ दर्शाता है।

अब तक, ggplot2 का उपयोग कर, मैं सिर्फ stat_density2d और geom_tile तरह के तरीकों, जो केवल बिंदु घनत्व को प्रदर्शित करने और समान रूप से अंक का प्रतिनिधित्व करने के लिए काम मिल सकता है (जहाँ तक मैं बता सकता हूँ)।

आदर्श रूप में यह इस छवि के रूप में एक ही सिद्धांत का पालन होगा:

जिसमें रंग आसपास के क्षेत्र में दिए गए अंक भले ही घनत्व और अंक की नियुक्ति एक समान नहीं था के आधार पर सौंपा गया।

मैं इस छवि की तरह मैट्रिक्स रूप में एक गर्मी नक्शा बनाने के लिए नहीं करना चाहती:

जिसमें एक मेज रंग कोडित है। इसके बजाय, मैं गैर-समान रूप से वितरित एक्स और वाई निर्देशांक का उपयोग करके निरंतर गर्मी मानचित्र बनाना चाहता हूं, असल में, उस सीमा को प्रदर्शित करता है जिसमें डेटा असीमित कई आयताकारों में टूट जाता है। यह फ़ंक्शन द्वारा उपयोग की जाने वाली वास्तविक विधि नहीं हो सकती है, लेकिन यह एक सामान्य विचार प्रदान करता है कि मैं क्या देख रहा हूं।

यहां कुछ नमूना डेटा है:

data=data.frame(x=c(1,1,2,2,3,4,5,6,7,7,8,9), 
    y=c(2,4,5,1,3,8,4,8,1,1,6,9), 
    distance=c(66,84,93,76,104,29,70,19,60,50,46,36)) 

मैं रंग का पैमाना है कि, संख्या की पूरी रेंज को शामिल किया गया है पहले कड़ी में भूखंड प्रदान की तरह के रूप में दूरी के साथ एक गर्मी नक्शा कैसे बना सकते हैं?

किसी भी मदद की बहुत सराहना की जाती है!

Answer 1

वहाँ

एक उपयोगकर्ता के प्रश्न के लिखित यहाँ समारोह है कि हीटमैप का उत्पादन ggplot2 का उपयोग कर रहा है:

और उनके उदाहरण छवि:

क्या यदि आप चाहते हैं एक टोपो नक्शे के रूप में है आपके उदाहरण में, इसके लिए बहुत सारे टूल हैं (बस "टॉपो मैप" के अंतर्गत खोजें।

और अंत में, वहाँ isarithmic नक्शा है, जो बस पता चलता है कि आप स्पष्ट करना कि वास्तव में आप क्या किया चाहते हैं तो आप कुछ समरेखण शामिल चाहते हैं की जरूरत है चला जाता है: http://dsparks.wordpress.com/2011/10/24/isarithmic-maps-of-public-opinion-data/

Answer 2

ggplot2::ggfluctuation(data, type="colour")

फिर आप करेंगे।

ggfluctuation(table(gamesWide$HomeLast, gamesWide$AwayLast), type="colour") + labs(x="Away", y="Home") + opts(title="Distribution of Last Digit of Score") 

बेशक

पाने के लिए, उस छवि को पूर्ण डेटासेट का उपयोग करके बनाया गया था। यह डेटा के लिए और अधिक समेकित होना चाहिए जो सममित और आयताकार नहीं है।

Answer 3

आदेश अनियमित से स्थान दिया गया निर्देशांक आप एक नियमित ग्रिड intrapolate करने के लिए पहली जरूरत है (यहाँ पैकेज akima के समारोह interp का प्रयोग करके) के साथ एक सतत मानचित्र उत्पन्न करने के लिए:

require(akima) 
data <- data.frame(x=c(1,1,2,2,3,4,5,6,7,7,8,9), 
        y=c(2,4,5,1,3,8,4,8,1,1,6,9), 
        distance=c(66,84,93,76,104,29,70,19,60,50,46,36)) 
resolution <- 0.1 # you can increase the resolution by decreasing this number (warning: the resulting dataframe size increase very quickly) 
a <- interp(x=data$x, y=data$y, z=data$distance, 
      xo=seq(min(data$x),max(data$x),by=resolution), 
      yo=seq(min(data$y),max(data$y),by=resolution), duplicate="mean") 
image(a) #you can of course modify the color palette and the color categories. See ?image for more explanation 

या आप उपयोग कर सकते हैं , जो अपने आप की साजिश रचने के लिए, filled.contour काम करते हैं:

filled.contour(a, color.palette=heat.colors)
