我一直在尝试制作一张美国地图,其中包含枪击事件的叠加散点图,每个点的 hoverinfo 标签中都有伤亡人数和受伤人数。但是,标签弹出为“num_killed”,我想将其格式化为“Number Killed:”。到目前为止,我已经尝试在 ggplot 部分标记变量,但无济于事。有什么方法可以更改工具提示中变量名称的打印方式吗?
这是我的代码:
library(plotly)
library(dplyr)
library(ggplot2)
us <- map_data("state")
library(maps)
g <- ggplot() +
geom_polygon(data = us, aes(x=long, y = lat, group = group), fill="grey", alpha=0.3) +
geom_point(data=shootings, aes(x=lng, y=lat, size = num_killed, color = num_injured)) +
labs(color = "Number Injured", size = "Number Killed", num_killed = "Number Killed", num_injured = "Number Injured")
plot <- ggplotly(g)

所附数据集是该数据库处理后的 csv:http : //www.gunviolencearchive.org/reports/mass-shooting? page =1 (作为数据框处理)。
我正在尝试创建一个程序来分配任何人类型以响应某个提示,它占用了两行以上而且我担心它不能识别字符串,因为它在不同的行上.它不断弹出"不正确的语法"错误并继续指向下面的行.我能解决这个问题吗?
given = raw_input("Is " + str(ans) + " your number?
Enter 'h' to indicate the guess is too high.
Enter 'l' to indicate the guess is too low.
Enter 'c' to indicate that I guessed correctly")

class Hero{
String name;
int Intelligence;
boolean parents;
public static fight(Hero1, Hero2){
if(Hero1.Intelligence>Hero2.Intelligence){
return(Hero1.name+" is the winner");
else
return(Hero2.name+" is the winner");
}
}
}
class HeroMain{
public static void main(String[] args){
Hero Superman = new Hero();
Superman.name = "Superman";
Superman.Intelligence = 7;
Superman.parents = false;
Hero Batman = new Hero();
Batman.name = "Batman";
Batman.Intelligence = 8;
Batman.parents = false;
public fight(Superman, Batman);
}
}

不幸的是,有人带来了Kryptonite :(

有人看到错误吗?如果是这样,请提前感谢任何答案; 下面的代码和错误的代码是四重引号:
class Hero{

int intelligence;
boolean parents;
double strength;
public static String fight(Hero hero1, Hero hero2){
if(hero1.intelligence+hero1.strength>hero2.intelligence+hero2.strength)
return(hero1.name+" is the winner");
else{
//If hero2 wins, initiate this code
