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:

x <- rnorm(100)
y <- rnorm(100)
plot(x,y)

plot(x,y,xlab="this is the x-axis",ylab="this is the y-axis",main='Plot of X vs Y')

x<-c(1:10)
x
##  [1]  1  2  3  4  5  6  7  8  9 10
y<-x^2
y
##  [1]   1   4   9  16  25  36  49  64  81 100
plot(x,y,xlab="this is x axis",ylab="this is y axis",main="plot of x and y")

plot(x,y,xlab="this is x axis",ylab="this is y axis",main="plot of x and y",type="l")

x<-c(-10:10)
y<-x^2
y
##  [1] 100  81  64  49  36  25  16   9   4   1   0   1   4   9  16  25  36  49  64
## [20]  81 100
plot(x,y,xlab="this is x axis",ylab="this is y axis",main="plot of x and y",type="l")

plot(x,y,xlab="this is x axis",ylab="this is y axis",main="plot of x and y",type="b")

plot(x,y,xlab="this is x axis",ylab="this is y axis",main="plot of x and y",type="p")

## Warning: Using size for a discrete variable is not advised.

ggplot(data = mpg)+geom_point(mapping=aes(x=displ,y=hwy,shape=class))
## Warning: The shape palette can deal with a maximum of 6 discrete values because more

##   that many have them.
## Warning: Removed 62 rows containing missing values or values outside the scale range
## (`geom_point()`).

Including Plots

You can also embed plots, for example:

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