I'm having difficulty getting plots into ioslides. It seems to me that the scale is completely out, but I can't figure out what to do about it. Whatever I try, I get the title slide, then a second with a horizontal line and a vertical line in the bottom right corner. It looks like a badly scaled plot about 25 times the size of the plotting area, so only a fragment is visible.
This is the code I've tried: --- title: "Barking up the wrong tree" author: "Patrick Connolly" date: "`r format(Sys.time(), '%a %d/%m/%Y %H:%M')`" output: ioslides_presentation --- ```{r global_options, echo=FALSE} knitr::opts_chunk$set(tidy=TRUE, warning=FALSE, message=FALSE, cache=FALSE, dpi=600) ``` ```{r use these functions, echo= FALSE} load(".RData") ## code for 6 plotting functions `` ## 6 different Trees ```{r 6 different Trees, echo = FALSE, messages=FALSE, fig.width = 7, fig.height = 5} ### par(mfrow = c(2, 3)) plot1() plot2() plot3() plot4() plot5() plot6() } ``` If I run the plot functions in the Console, it all works and displays correctly in Rstudiio's plot panel, even the mfrow bit. But I haven't worked out how to include the code into Rmarkdown. I thought it might be less taxing to not try putting the 6 plots on the same slide, but it makes no difference when I commented out the mfrow bit. I'm not very familiar with the workings of Markdown or Rstudio, but it does seem strange to me that I need to specifically load the global environment otherwise it's not visible. Is that to be expected? Ideas welcome, particularly about scaling. -- ~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~. ___ Patrick Connolly {~._.~} Great minds discuss ideas _( Y )_ Average minds discuss events (:_~*~_:) Small minds discuss people (_)-(_) .....
