Base Graphics:
plot(x,y,type="n")
segments(x[-length(x)],y[-length(x)],x[-1],y[-length(x)])
points(x[-length(x)],y[-length(x)],pch=16)
points(x[-1],y[-length(x)],pch=1)
Ggplot graphics:
library(ggplot2)
dta <- data.frame( x= x[-length(x)],y=y[-length(x)], xend=x[-1],
yend=y[-length(x)] )
ggplot( dta, aes( x=x, y=y, xend=xend, yend=yend )) +
geom_segment()+
geom_point( shape=16, size=4 ) +
geom_point( aes( x=xend, y=yend, shape=1, size=4 )
There is also lattice graphics, but I don't feel like putting that example
together right now.
As for how to use RStudio, please understand that RStudio has its own support
forums. Please direct questions regarding that user interface there, and
remember that the people answering questions here may be using completely
different tools and operating systems than you are. I strongly recommend
reading the R-help posting guide and reading other people's questions here to
get the flavor of the kinds of question and answer format is preferred around
here. Hint: this is a mailing list, not Nabble.
Easy tutorials? There are lots of them, but they don't necessarily get you
where you want to go. I recommend reading the Introduction to R document that
comes with R, with particular focus on vectors, lists, matrices, data frames,
and indexing. The apply family of functions will also be useful, but vectors
and indexing are first priority. They all work together to make a very powerful
combination, and learning those fundamentals will pay off in helping you
decipher examples such as that ones above.
