    • new file will start with a minimal reproducible presentations

Slide with Bullet Points

For more details on authoring R presentations click the Help button on the toolbar.

  • Bullet 1 required a space after - sign
    • sub bullet
      • sub-sub bullet required three more spaces
  • Bullet 2. Try to keep bullets simple
  • Bullet 3. Try not to write bullet more than a line
    • bullet does not have to be a complete sentence

Slide With R Code

Slide With python or Linux command

  • This is a python command. Notice how we changed the engine to python
print "Hellow R"

Hellow R
  • This is a Linux command. Notice how we changed the engine to bash
pwd

  • You can use other commands like C, awk etc.

Slide With Plot

  • Notice how the size of the plot is set plot of chunk unnamed-chunk-4

Slide With two columns

  • First column has a plot but no R code plot of chunk unnamed-chunk-5

  • Notice the first column is wider since left is set to be 70%

  • My Second column shows R code with results
head(women)

  height weight
1     58    115
2     59    117
3     60    120
4     61    123
5     62    126
6     63    129
  • second column is narrow
    • but why?

Slide with a table created from dataframe

  • This will show the head of dataframe mtcars in a table
library(knitr)
kable(head(mtcars), format="html")
mpg cyl disp hp drat wt qsec vs am gear carb
Mazda RX4 21.0 6 160 110 3.90 2.620 16.46 0 1 4 4

Slide with a user defined table

  • Notice in the codes, how this table is generated
package functions
base sample, union, intersect, rbind, unique, merge
plyr mutate, transmute
reshape2 melt, dcast
plyrmr bind.cols, transmute, select, where, count.cols, quantile.cols, top.k, bottom.k

Slide with math equation

The normal distribution can be written as

\[ f(x)=\frac1{\sqrt{2\pi \sigma^2}} e^{-\frac1{2\sigma^2} (x-\mu)^2} \]

Symbolically we write \[ X \sim N(\mu, \sigma^2) \]

Slide with HTML
