Simplicity: Turning an existing Web site into a channel merely involves creating a CDF file with a text editor and creating a hyperlink to this file.Structure: CDF describes how to logically group information in a hierarchical structure, independent of the content format.User control: The user can use CDF to specify which portions of a site to download to his or her browser, instead of pulling a lot of content off the site and hoping that it contains the needed information.Administrator control: The administrator can control how much of the site can be downloaded by users.Personalization: Standard Hypertext Transfer Protocol (HTTP) cookies can be used to deliver personalized information to users.

Species="Homo_sapiens", unlink=TRUE, compress=FALSE, package.path = pkgpath) ("mirna40cdf", version = packageDescription("makecdfenv", field = "Version"), How can I fix this? Here's the full code: require(affy)ĬonvertCdf("miRNA-4_0-st-v1.cdf", "mirna40cdf", version=4, verbose=TRUE) Warning message:missing cdf environment! in show(AffyBatch) Library - package mirna40cdf not installed Specified environment does not contain miRNA-4_0 So I tried the function, but ReadAffy doesn't work properly and gives me this error: names <- dir(pattern = "*.CEL", path="~/cell/GSE143564_RAW",full.names = TRUE)Ĭould not obtain CDF environment, problems encountered:
