如何获得一定年份之间的所有数据？例如，我需要1970-2010年之间的数据

Question

我正在创建一个图表，显示不同国家（1970-2010年）在某些年份之间的预期寿命的增长以及医疗保健的费用，但是我无法找到一种方法来获得指定年份之间的数据。 另外，这里是查看数据集的链接（如果有帮助的话）：https://ourworldindata.org/grapher/life-expectancy-vs-health-expenditure

data <- read.csv("file:///C:/Users/Gavyn Henderson/Downloads/life-expectancy-vs-health-expenditure.csv")

names(data) <- c("Country","CountryABV","Year","LifeExpextancy","Expenditure","Population")

data$Expenditure    <- as.numeric(levels(data$Expenditure))[data$Expenditure]


sub1 <- subset(data, CountryABV == "USA"|CountryABV == "GBR"|CountryABV == "DEU"|CountryABV == "FRA"|
                 CountryABV == "JPN"|CountryABV == "AUS"|CountryABV == "CHE"|CountryABV == "CAN")
sub2 <- subset(data, Year %in% 1970:2010)

gg <- ggplot(sub1) + aes(Expenditure, LifeExpextancy,frame = sub2, color = Country) +
  geom_point(aes(size = Population)) + xlab("Life Expectance") + 
  ylab("Health Expenditure") +
  ggtitle("Life Expectance vs. Health Expenditure") +
  ylim(65,85) + 
  xlim(0,8000)
ggplotly(gg)
