Once a source package is created, it must be installed by the command . This example demonstrates use of several different R packages that provide functions for reading and/or writing shapefiles. Many volunteers have contributed to the packages used here.

## Write a file in r

You need to keep track and deliberately set your working directory in each R session. The principal author of this manual was Brian Ripley.

Write.table(x,file= "", append = FALSE, quote = TRUE, sep = " ", eol = "\n", na = "NA", dec = ".", row.names = TRUE, col.names = TRUE, qmethod = c("escape", "double"),fileEncoding = "")write.csv(...)write.csv2(...) , any character or factor columns will be surrounded by double quotes.

The relational databases part of this manual is based in part on an earlier manual by Douglas Bates and Saikat Deb Roy. The ESRI Shapefile is a widely used *file* format for storing vector-based geopatial data (i.e., points, lines, and polygons).

I would like a summary output **file** such as: out.summary.txtwhere column 1 is chromosome, column 2 is start of region, column 3 is end of region, column 4 is total reads in general, column 5 is total reads =1, column 6 is (col4/col5) or the percentage, and at the end I'd like to list 6 more columns based on summary results from summary() function in R. If any of you have any suggestions I would appreciate it.
