multiple (R) plotly figures generated in a rmarkdown (knitr chunk) document

Question

I try to create multiple plotly figures in a Rmarkdown document using loop or lapply.

The R script:

require(plotly)
data(iris)
b <- lapply(setdif         


        

Answer 1

For anyone struggling with a loop, here's what worked for me.

p=list()
for (n in 1:3){
  p[[n]] <- plot_ly(x = 1:100, y = rnorm(100)+n, mode = 'lines', type="scatter")
}
htmltools::tagList(p)

I.e. it doesn't matter if the list p is created in a loop or lapply, etc. as long as you call htmltools::tagList outside the loop.

Thanks to Yihui for helping me get there and for immense work developing and helping with these tools.
