Dear Aimin, Your question about Excel comes up rather often on the list and answers can be found in the archives in the "R Data Import/Export" PDF file installed with R. In short, you can read CSV files through read.csv or you can get read directly from Excel spreadsheets through the excellent RODBC package. Documentation suitable for R beginners is installed by default (look for the PDF file "An Introduction to R") and there is much additional material available on the CRAN website. Also, try ?histogram for more detailed information.
