我正在尝试获取一个wordcloud,其中wordcloud的颜色基于数据框中的另一列。因此,我正在使用wordcloud2和RColorBrewer软件包。我正在使用以下(示例)代码:
set.seed(1)
DF <- data.frame(
word = c('football','tennis','squash','curling','baseball','diving','archery','cricket','cycling','hockey','formula1','rugby','volleyball','tabletennis','swimming','shooting','taekwondo','judo','handball','horseracing'),
freq = sample(100:1000,20),
diff = sample(-100:100,20)/100)
library(wordcloud2)
library(RColorBrewer)
color_range_number <- length(unique(DF$diff))
custColorPal <- colorRampPalette(c("#ff0000","#00cc00"))
custColors <- custColorPal(color_range_number)
colors <- custColors[factor(DF$diff)]
wordcloud2(data = DF, color = colors)
DF如下:
word freq diff
1 football 339 0.87
2 tennis 434 -0.58
3 squash 614 0.29
4 curling 915 -0.76
5 baseball 280 -0.48
6 diving 904 -0.25
7 archery 945 -0.98
8 cricket 690 -0.26
9 cycling 661 0.67
10 hockey 155 -0.35
11 formula1 283 -0.08
12 rugby 257 0.13
13 volleyball 710 -0.07
14 tabletennis 441 -0.65
15 swimming 782 0.54
16 shooting 540 0.24
17 taekwondo 735 0.46
18 judo 976 -0.81
19 handball 435 0.32
20 horseracing 785 0.93
在DF中,我想使用“ diff”列为单词分配颜色:负值越大,红色越多,正值越大,绿色越多。
但是,我得到了意想不到的结果,例如'曲棍球'被涂成绿色,而由于变量'diff'的diff值为-0.35,因此它应该具有更多的红色。另请参见this screenshot。
我认为这是由于没有绘制所有单词,因为例如没有绘制“ horseracing”。
我的问题:
答案 0 :(得分:0)
第class myService
{
private $accessGranted;
public function __construct(Security $security)
{
// user might not be set up yet?
$accessGranted = $security->isGranted('ROLE_ADMIN');
}
public function someFunctionWithSecurity()
{
if( $accessGranted )
// do the admin stuff here
else
// do slightly different stuff here
}
}
行引起了我认为的问题。试试这个...
const functions = require('firebase-functions');
const admin = require('firebase-admin');
admin.initializeApp();
exports.sendNotification = functions.https.onRequest((request, response) => {
const payLoad = {
data: {
execute_noise_measure: "true"
}
};
const options = {
priority: "high"
};
return admin.messaging().sendToTopic("all", payLoad, options).then(function(response) {
return console.log("Successfully sent message:", response);
})
.catch(function(error) {
return console.log("Error sending message:", error);
});
});
所有custColorPal函数所做的只是查找diff值以在颜色范围内缩放它。因子被解释为等距的数字,范围为1到20。
关于第二个问题,我的建议是使字体变小,以便更有可能显示所有单词
