missing waterfallgap attributes in plotly package

[Mahdis-z]

It seems that waterfallgroupgap and waterfallgap attributes were not added to Plotly package. https://plot.ly/r/reference/#layout-waterfallgroupgap. Running this code gives a warning saying so.

library(plotly)

y = c(375, 128, 78, 0, -327, -78, 0, 32, 89, 0, -45, 0)
x = c("Sales", "Consulting", "Maintenance", "Net revenue", "Purchases", "Material expenses", "Operating profit", "Investment income", "Financial income",
"Profit before tax", "Income tax (15%)", "Profit after tax")
measure = c("relative", "relative", "relative", "total", "relative", "relative", "total", "relative", "relative", "total", "relative", "total")
data = data.frame(x=factor(x,levels = x), y, measure)

P <- plot_ly(data, x = ~x, y = ~y, measure = ~measure, type = "waterfall", base = 300, decreasing = list(marker = list(color = "Maroon", line = list(color = "red", width = 2))),
increasing = (marker = list(color = "Teal")),
totals = list(marker = list(color = "deep sky blue", line = list(color = 'blue', width = 3))))%>%
layout(title = "Profit and loss statement", xaxis = list(title = "", tickfont = "16", ticks = "outside"),
yaxis = list(title = ""), waterfallgap = "0.3")
P

This warning is actually a false positive (e.g., if you compare the result of waterfallgap = 0 andwaterfallgap = 1, the attribute is having the desired effect).

Closing since this is a duplicate of #994.
