```r library(plotly) library(crosstalk) txhousing %>% group_by(city) %>% SharedData$new(~city, "Select a city") %>% plot_ly(x = ~date, y = ~median) %>% add_lines(alpha = 0.2) %>% add_ribbons( x = c(2016, 2017), ymin = c(150000, 160000), ymax = c(200000, 190000), inherit = FALSE ) ``` ```r Error: Columns `x`, `ymin`, `ymax` must be length 1 or 8602, not 2, 2, 2 ``` This error isn't very helpful -- the error is occuring because the ribbon trace is inheriting the crosstalk key, but it shouldn't...
