![]() Please note that images and tables will always be placed on new slides. You can generate most elements supported by Pandoc’s Markdown (Section 2.5) in PowerPoint output, such as bold/italic text, footnotes, bullets, LaTeX math expressions, images, and tables, etc. ![]() You can also start a new slide without a header using a horizontal rule. The default slide level (i.e., the heading level that defines individual slides) is determined in the same way as in Beamer slides (Section 4.3.2), and you can specify an explicit level via the slide_level option under powerpoint_presentation. 19.7 Output arguments for render functionsįIGURE 4.5: A sample slide in a PowerPoint presentation.16.5.4 Create a widget without an R package.2.1.4 2017 Employer Health Benefits Survey.Similarly, change “pdf” to “word.” A Word document should be produced. In the header (YAML), change the word “html” to “pdf” and re-knit the file. The IRT item characteristic curves are plotted below.Ĭopy the above lines and save them as a Rmd file. The TAM distractor analysis is shown below P <- wrightMap(mod1$WLE,mod1$xsi,item.side=itemClassic) The following is a table of IRT item difficulties. The following is a table of CTT item analysis. The CTT test reliability is `r IA$alpha`. In this data set, there are `r mod1$nitems` items and `r mod1$nstud` students. To run R code in R markdown, we need to enclose the R code inside a R code chunk starting and ending with three back-ticks `. To do that we will need to run some R code. We will analyse the numeracy data provided by the R package TAM.
