Welcome to R. Coming from an S background you should have no problems
to adjust quickly. For data import have a look at the "R Data
Import/Export" manual:

http://cran.r-project.org/doc/manuals/R-data.html

Plotting is not to different from S-Plus. As far as my knowledge goes
there are 3 differnet plotting frameworsk in R:

1) "Basic" plot functions like plot or hist some of which are covered in 
the Introduction to R

2) lattice (the R aequivalent of trellis graphics

covered in many manual pages, many tutorials and talks google will
quickly find and last but not least the book
"Lattice: Multivariate Data Visualization with R" by Deepayan
Sarkar who implemented lattice

3) ggplot2

See http://had.co.nz/ggplot2/ for documentation
and consider the book "ggplot2: Elegant Graphics for Data Analysis" by
Hadley Wickham (the author of ggplot2)


I use all three frameworks on a regular basis - choosing the
respective functions depending on the complexity of the task.
