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:

hist(rnorm(1000))

library(lattice)

#
dta <- Chem97

#
dta$age = dta$age + 18.5

#
histogram(~gcsescore | factor(score), data=dta)

#
tp1 <- histogram(~gcsescore | factor(score), data=dta)

#
tp2 <- densityplot(~ gcsescore, 
                   groups=score, 
                   data=dta, 
                   plot.points=F, 
                   auto.key=list(space="right",title="score"))

# (col.position, row.position, n.col, n.row)
plot(tp1, split=c(1,1,1,2))

# put the second trellis obj at row 2
plot(tp2, split=c(1,2,1,2), newpage=F)
