acharts

Make Virtual Reality Charts with R.

Installation

# install.packages("devtools")
devtools::install_github("JohnCoene/acharts")

Example

Scatter and bar example, first generate somewhat random data.

library(aframer)
library(acharts)

COL <- round(runif(20, 1, 5))
HEIGHT <- runif(20, 1, 10)

scatter <- data.frame(
  x = runif(20, 1, 5),
  y = runif(20, 5, 10),
  z = runif(20, 1, 20),
  size = runif(20, .1, .4),
  color = COL
)

bar <- data.frame(
  x = runif(20, 1, 5),
  y = HEIGHT - (HEIGHT/2),
  z = runif(20, 1, 20),
  height = HEIGHT,
  color = COL
)

f <- function(){
    runif(20, 1, 10)
}

line <- data.frame(
    src.x = f(),
    src.y = f(),
    src.z = f(),
    tgt.x = f(),
    tgt.y = f(),
    tgt.z = f()
)

labels <- scatter
labels$z <- labels$z + 1 # off by a meter
labels$text <- glue::glue("height: {round(labels$y)}m")

Then plot.
