问题
I am using RStudio version 0.98.501, R version 3.0.2 on Windows 7. I have following code written in a .Rmd file:
---
title: "Sample Document"
output:
html_document:
toc: true
theme: united
---
Title
========================================================
This is an R Markdown document. Markdown is a simple formatting syntax for authoring web pages (click the **Help** toolbar button for more details on using R Markdown).
When you click the **Knit HTML** button a web page will be generated that includes both content as well as the output of any embedded R code chunks within the document. You can embed an R code chunk like this:
```{r}
summary(cars)
```
You can also embed plots, for example:
```{r fig.width=7, fig.height=6}
plot(cars)
```

When I click knitHtml button the created html file DOES NOT contain the table of contents. However when I use following code, it creates the table of contents and change the theme to united:
rmarkdown::render('C:/Users/durraniu/Documents/Trajectory1/knitHtml/test.Rmd')
What is the difference and how can I make knitHtml button work the way the code does?

RStudio version 0.98.501 does not support the rmarkdown package. You have to check out the latest preview version (at this moment, v0.98.894).
