Is there a way to hide Trace Names in Plotly (specifically R)?

Question

I've been wracking my brain over how to get rid of the trace name with plotly and can't seem to find anything. It seems adding the trace name is a unique feature of plotly boxplots. I could just name it " " but I need the original trace name so that I can reference it when overlaying a marker. I've simplified the code as much as possible to the root issue. Is there a way to hide the trace name?

housing = read.table("http://archive.ics.uci.edu/ml/machine-learning-databases/housing/housing.data")
colnames(housing) = c("CRIM","ZN","INDUS","CHAS","NOX","RM","AGE","DIS","RAD","TAX","PTRATIO","B","LSTAT","MEDV")

housing %>%
  plot_ly( x = ~RM, 
        type="box", 
        name = "RM",
        showlegend = FALSE
        ) %>% 
  add_markers(x=6, y="RM",
            marker = list(color = "blue", size = 15)
            )

Welcome to Stackoverflow! Where are you trying to hide the trace name? In the y-axis or in the hover info? — Maximilian Peters, Aug 29 '18 at 16:45
Thanks Max! I'm trying to hide the trace name on the y-axis. Hover Info can be customized in the Layout if I remember correctly so I'm not too worried about that. — robotvsbears, Aug 30 '18 at 17:48

If you want to hide the trace names in a box chart, you could hide the axis' labels by using showticklabels = F.

In the example below the trace name is also hidden in the hover labels by setting hoverinfo = 'x'.

library(plotly)
housing = read.table("http://archive.ics.uci.edu/ml/machine-learning-databases/housing/housing.data")
colnames(housing) = c("CRIM","ZN","INDUS","CHAS","NOX","RM","AGE","DIS","RAD","TAX","PTRATIO","B","LSTAT","MEDV")

housing %>%
  plot_ly( x = ~RM,
           y = 'RM',
           type="box", 
           name = "RM",
           showlegend = FALSE,
           hoverinfo = 'x'
  ) %>% 
  add_markers(x=6, y="RM",
              marker = list(color = "blue", size = 15)
  ) %>% layout(yaxis = list(showticklabels = F))
housing

Thank you Maximillian you rule! – robotvsbears Sep 05 '18 at 18:59 — robotvsbears, Sep 05 '18 at 18:59
