shiny - Reactive input to ggvis in R-markdown cause quit -


i'm trying use r-markdown shiny interactive visualization. file let user specify bunch of data files , use reactive shiny expression processed dataframe, data(). can use data() renderplot correctly plot out bunch of graphs(like heatmap.2, plot). however, when try using ggvis plot reactive data, generation of html quit @ ggvis code chunk. tried answer how data passed reactive shiny expression ggvis plot?. both of 2 methods in answer led "quitting lines". here's code:

reactive({     data %>% ggvis(~pcomp, ~variances) %>%      layer_points()%>%     layer_bars(fill := "gray", opacity := 0.5) %>%     layer_lines() }) %>% bind_shiny("plot1")  ggvisoutput("plot1") 

here's code based on other method:

data %>% ggvis(~pcomp, ~variances) %>%      layer_points()%>%     layer_bars(fill := "gray", opacity := 0.5) %>%     layer_lines() 

i'm using r-studio version 0.99.441, r version 3.2.1 (2015-06-18), shiny_0.12.1, ggvis 0.4.

switched pure shiny , retried this, instead of using reactive, wrapped whole thing in observe. works perfectly.
