我正在尝试在 rbokeh 中制作自定义工具提示,但是当我尝试以编程方式进行时,非标准评估会妨碍我。
从例子:
library(rbokeh)
mtcars$model <- row.names(mtcars)
figure() %>%
ly_points(disp, mpg, data = mtcars, color = cyl,
hover = "This <strong>@model</strong><br>has @hp horsepower!")
Rbokeh 有助于在悬停时填充@model
变量@hp
。但是,当我尝试使悬停时使用可以即时更改的字符串,例如:
hover_text <- "This <strong>@model</strong><br>has @hp horsepower!"
mtcars$model <- row.names(mtcars)
figure() %>%
ly_points(disp, mpg, data = mtcars, color = cyl,
hover = hover_text)
rbokeh 未正确填写工具提示中的变量。
如何让 rbokeh 将hover_text
其视为与原始字符串相同?
我已经尝试了几种变体do.call
,但它们都有错误。
ly_points_docall <- function(...) {
do.call(ly_points, list(..., hover = hover_text))
}
figure() %>%
ly_points_docall(disp, mpg, data = mtcars, color = cyl,
hover = hover_text)
# Error in do.call(ly_points, list(..., hover = hover_text)) :
# object 'disp' not found
和
ly_points_docall <- function(...) {
do.call(ly_points, list(..., hover = hover_text))
}
figure() %>%
ly_points_docall(~disp, ~mpg, data = mtcars, color = ~cyl,
hover = hover_text)
# Error in (function (fig, x, y = NULL, data = figure_data(fig), glyph = 21, :
# formal argument "hover" matched by multiple actual arguments
