我在rmaps中使用了ichoropleth函數[https://github.com/ramnathv/rMaps/blob/master/R/Datamaps.R#L43]來構建動畫choropleth。我想按月而不是按年來動畫。爲了實現這一點,我已經將代碼中的術語年的所有實例更改爲月份。顯示第一個月的數據,但動畫不會播放。如果我的代碼更改是正確的,我懷疑問題可能是以月爲因素,但我不能將其轉換爲數字或日期,同時保留正確的格式。誰能提供解決方案?我的數據的樣品低於rmaps以月份爲單位生成choropleth

structure(list(month = structure(c(1L, 1L, 1L, 1L, 1L, 1L), .Label = c("2013-03",

當我使用提供的數據我得到一個data.frame的6行所有月份2013-03。我會盡力讓一些假數據重現。 – timelyportfolio 2014-09-11 15:02:26

我會盡力做一個完全可重複的代碼示例包括以上你的問題位。

首先,設置您提供的數據。

dt <- structure(list(month = structure(c(1L, 1L, 1L, 1L, 1L, 1L), .Label = c("2013-03", 
"2013-04", "2013-05", "2013-06", "2013-07", "2013-08", "2013-09", 
"2013-10", "2013-11", "2013-12", "2014-01", "2014-02", "2014-03", 
"2014-04", "2014-05", "2014-06", "2014-07", "2014-08"), class = "factor"), 
iso = structure(c(2L, 5L, 6L, 7L, 8L, 15L), .Label = c("ABW", 
"AFG", "AGO", "AIA", "ALB", "ARE", "ARG", "AUS", "AUT", "AZE", 
"BEL", "BEN", "BFA", "BGD", "BGR", "BHR", "BHS", "BIH", "BLR", 
"BLZ", "BMU", "BRA", "BRB", "BWA", "CAF", "CAN", "CHE", "CHL", 
"CHN", "CMR", "COL", "COM", "CRI", "CUB", "CYM", "CYP", "CZE", 
"DEU", "DJI", "DMA", "DNK", "DOM", "DZA", "ECU", "EGY", "ERI", 
"ESP", "EST", "ETH", "FIN", "FJI", "FRA", "FRO", "GAB", "GBR", 
"GEO", "GGY", "GHA", "GIB", "GIN", "GLP", "GMB", "GNQ", "GRC", 
"GRD", "GTM", "GUF", "GUM", "GUY", "HKG", "HND", "HRV", "HTI", 
"HUN", "IDN", "IMN", "IND", "IRL", "IRQ", "ISL", "ISR", "ITA", 
"JAM", "JEY", "JOR", "JPN", "KAZ", "KEN", "KGZ", "KHM", "KWT", 
"LBN", "LBR", "LBY", "LCA", "LKA", "LSO", "LTU", "LUX", "LVA", 
"MAR", "MCO", "MDV", "MEX", "MLI", "MLT", "MMR", "MNG", "MOZ", 
"MRT", "MUS", "MWI", "MYS", "NAM", "NCL", "NER", "NGA", "NIC", 
"NLD", "NOR", "NPL", "NZL", "OMN", "PAK", "PAN", "PER", "PHL", 
"PNG", "POL", "PRI", "PRT", "PRY", "QAT", "ROU", "RWA", "SAU", 
"SDN", "SEN", "SGP", "SLB", "SLE", "SLV", "SOM", "SRB", "SSD", 
"SUR", "SVK", "SVN", "SWE", "SYC", "TGO", "THA", "TJK", "TKM", 
"TON", "TTO", "TUN", "TUR", "UGA", "UKR", "URY", "USA", "UZB", 
"VNM", "VUT", "WSM", "YEM", "ZAF", "ZMB", "ZWE"), class = "factor"), 
volume = c(1L, 1L, 5L, 4L, 12L, 10L)), .Names = c("month", 
"iso", "volume"), row.names = c(NA, 6L), class = "data.frame") 

這個數據雖然只包含了所有同月6行,所以我用你iso(ISO國家代碼)和month提供的水平做了一些假數據。我會把它叫做dt2。爲了將來的參考,提供可用數據是非常有用的。

dt2 <- data.frame(
    iso = as.factor(rep(levels(dt$iso),length(levels(dt$month)))) 
    ,month = unlist(lapply(1:length(levels(dt$month)),function(m){ 
     rep(levels(dt$month)[m],length(levels(dt$iso))) 
    })) 
    ,volume = runif(length(levels(dt$month))*length(levels(dt$iso)),0,100) 
) 

如果你需要factors讓我知道,但它使用普通rChartsrMapsJSON時一般是明智的因素轉化爲numericcharacter值。

# no reason to have factors 
    # so I suggest converting to character 
    dt2$iso <- as.character(dt2$iso) 
    dt2$month <- as.character(dt2$month) 

你是從使用的因素,這些問題的結果是正確的,但更具體地講,ichorolpleth功能預計數字而不是字符。有多種方法可以解決這些問題。我選擇了這條路

Mchoropleth <- function(x, data, pal = "Blues", ncuts = 5, animate = NULL, play = F, map = 
    'world', legend = TRUE, labels = TRUE, ...){ 
    d <- Datamaps$new() 
    fml = lattice::latticeParseFormula(x, data = data) 
    data = transform(data, 
    fillKey = cut(
     fml$left, 
     unique(quantile(fml$left, seq(0, 1, 1/ncuts))), 
     ordered_result = TRUE 
    ) 
    ) 
    fillColors = RColorBrewer::brewer.pal(ncuts, pal) 
    d$set(
    scope = map, 
    fills = as.list(setNames(fillColors, levels(data$fillKey))), 
    legend = legend, 
    labels = labels, 
    ... 
    ) 
    if (!is.null(animate)){ 

    range_ = sort(unique(data[[animate]])) 


    data = dlply(data, animate, function(x){ 
     y = toJSONArray2(x, json = F) 
     names(y) = lapply(y, '[[', fml$right.name) 
     return(y) 
    }) 
    d$set(
     bodyattrs = "ng-app ng-controller='rChartsCtrl'" 
    ) 
    d$addAssets(
     jshead = "http://cdnjs.cloudflare.com/ajax/libs/angular.js/1.2.1/angular.min.js" 
    ) 
    if (play == T){ 
     d$setTemplate(chartDiv = sprintf(" 
     <div class='container'> 
     <button ng-click='animateMap()'>Play</button> 
     <div id='{{chartId}}' class='rChart datamaps'></div> 
     </div> 
     <script> 
      function rChartsCtrl($scope, $timeout){ 
      $scope.keynum = %s; 
       $scope.animateMap = function(){ 
       if ($scope.keynum === Object.keys(chartParams.newData).length){ 
       return; 
       } 
       map{{chartId}}.updateChoropleth(chartParams.newData[Object.keys(chartParams.newData)[$scope.keynum]]); 
       $scope.keynum += 1 
       $timeout($scope.animateMap, 1000) 
      } 
      } 
     </script>", 0 ) 
    ) 

    } else { 
     d$setTemplate(chartDiv = sprintf(" 
     <div class='container'> 
      <input id='slider' type='range' min=%s max=%s ng-model='value' width=200> 
      <div id='{{chartId}}' class='rChart datamaps'></div> 
     </div> 
     <script> 
      function rChartsCtrl($scope){ 
      $scope.month = %s; 
      $scope.$watch('month', function(newMonth){ 
       map{{chartId}}.updateChoropleth(chartParams.newData[newMonth]); 
      }) 
      } 
     </script>", range_[1], range_[6], range_[1]) 
    ) 
    } 
    d$set(newData = data, data = data[[1]]) 

    } else { 
    d$set(data = dlply(data, fml$right.name)) 
    } 
    return(d) 
    } 

要隔離位是重要的,我將在下面貼吧,這樣我可以通過它說話。 range_不上字符工作總結使用的,所以我把它改成

range_ = sort(unique(data[[animate]])) 

我們實際上可以消除這種,但那是另一個話題。然後$scope.month += 1將不起作用,因爲我們正在使用字符,所以我通過索引來遍歷數據的關鍵字。我們從$scope.keynum = %s開始,我們將其設置爲0,然後添加1 $scope.keynum += 1,直到我們到達末尾$scope.keynum === Object.keys(chartParams.newData).length

 d$setTemplate(chartDiv = sprintf(" 
     <div class='container'> 
     <button ng-click='animateMap()'>Play</button> 
     <div id='{{chartId}}' class='rChart datamaps'></div> 
     </div> 
     <script> 
      function rChartsCtrl($scope, $timeout){ 
      $scope.keynum = %s; 
       $scope.animateMap = function(){ 
       if ($scope.keynum === Object.keys(chartParams.newData).length){ 
       return; 
       } 
       map{{chartId}}.updateChoropleth(chartParams.newData[Object.keys(chartParams.newData)[$scope.keynum]]); 
       $scope.keynum += 1 
       $timeout($scope.animateMap, 1000) 
      } 
      } 
     </script>", 0 ) 
    ) 

這些R + Javascipt + Angular可能很難調試,所以我希望這有助於。我假設你看到這個post explaining some of what is happening,但我會張貼,如果你沒有。
