This is an attempt to set up a chunk hook for adding plots to the recordr data store "invisibly."
Currently, this hook function works for the last ggplot object plotted.
library(recordr) library(histry) kt = knitr_tracker() vtdb = jsonVTDB(tempfile(), img_dir = tempdir()) defaultVTDB(vtdb)
library(knitr) knit_hooks$set(plot = recordr:::recplothook) opts_chunk$set( out.width='\\textwidth', fig.height=8, fig.width=12.8, dpi=300, # tidy.opts=list(width.cutoff=200), # global.device = TRUE, fig.align='center', message=FALSE, cache=2 )
library(ggplot2) qplot(speed, dist, data = cars)
p = qplot(speed, dist, data = cars) p = p + geom_smooth() p + geom_jitter()
