R Markdown

This is an R Markdown document. Markdown is a simple formatting syntax for authoring HTML, PDF, and MS Word documents. For more details on using R Markdown see http://rmarkdown.rstudio.com.

When you click the Knit button a document 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:

xtrigramDF <- readRDS("/home/dugi/coursera/Course10/data/final/en_US/trigramDF.rds")

Including Plots

You can also embed plots, for example:

ggplot(xtrigramDF[1:30,], aes(factor(unigram, levels=unique(unigram)), freq)) +
  geom_bar(stat="identity", fill="purple", colour="black", width=0.9) +
  theme(axis.text.x=element_text(angle=90)) +
  labs(x="Trigram", y="Frequency", title="TEST - 30 Most Common Triple Words")

Note that the echo = FALSE parameter was added to the code chunk to prevent printing of the R code that generated the plot.
