Creating package in C:/Users/neurooncolab new pc/Documents/R/win-library/2.10/hugene10stv1.r3cdf README PLEASE: A source package has now been produced in C:/Users/neurooncolab new pc/Documents/R/win-library/2.10/hugene10stv1.r3cdf. Before using this package it must be installed via 'R CMD INSTALL' at a terminal prompt (or DOS command shell). If you are using Windows, you will need to get set up to install packages. See the 'R Installation and Administration' manual, specifically Section 6 'Add-on Packages' as well as 'Appendix E: The Windows Toolset' for more information. Alternatively, you could use make.cdf.env(), which will not require you to install a package. However, this environment will only persist for the current R session unless you save() it. > Rcmd install hugene10stv1.r3cdf Error: unexpected symbol in "Rcmd install" > R CMD INSTALL hugene10stv1.r3cdf Error: unexpected symbol in "R CMD" > RCMD INSTALL hugene10stv1.r3cdf Error: unexpected symbol in "RCMD INSTALL" > hugene10stv1.r3 = make.cdf.env("HuGene-1_0-st-v1.r3.cdf") Reading CDF file.
