Dmitry,
There is a complete R manual that describes how to get data into and
out of R, called R Data Import/Export. It is available within your R
distribution (if on Windows, via the R menus) or on the R web site at:
http://cran.r-project.org/manuals.html
There is also a page on the R Wiki at:
http://wiki.r-project.org/rwiki/doku.php?id=tips:data-io:ms_windows
which specifically covers R and Windows/Excel data exchange.
A quick example, if the above is in Notepad, but with NO BLANK LINE
between the x and y labels and the data. You can highlight the text,
press CTRL-C to copy it to the clipboard and then use the following in
R (see ?read.table):
DF <- read.table("clipboard", header = TRUE)
That will give you a 'data frame' in R that contains the two columns,
which can then be addressed as DF$x and DF$y. Further information is
available in the R manual An Introduction to R.
HTH,
