ggvis用ISO / IEC 8859-1绘制

Question

R的默认编码是ISO / IEC 8859-1，它允许我处理包含诸如åäö等字母的数据。但是，ggvis不允许这样的信件。

正如预期的那样，使用r plot

没有问题

data <- data.frame(Ålder = c(24:34), x = c(1:11))

plot(data$Ålder, data$x)

但是，当使用ggvis做同样的事情时，Å会被问号替换

data %>%
  ggvis(~Ålder, ~x)%>%
  layer_points()

是否可以将ggvis与ISO / IEC 8859-1编码一起使用？

此行为可能出现在32位计算机上。
