I am attempting to do a pathway analysis using KEGG on my results from DESeq2. I have run into some trouble installing the keggrest package from biocLite in R. The error i am getting from Rstudio is:
> library(KEGGREST) Error in loadNamespace(j <- i[[1L]], c(lib.loc, .libPaths()), versionCheck = vI[[j]]) : there is no package called ‘httr’ Error: package or namespace load failed for ‘KEGGREST’
I thought that the thing to do would be to install the httr package, but when I tried to do that I came across the following error:
> install.packages("httr") trying URL 'http://cran.rstudio.com/bin/macosx/mavericks/contrib/3.1/httr_0.6.1.tgz' Warning in install.packages : cannot open: HTTP status was '404 Not Found' Error in download.file(url, destfile, method, mode = "wb", ...) : cannot open URL 'http://cran.rstudio.com/bin/macosx/mavericks/contrib/3.1/httr_0.6.1.tgz' Warning in install.packages : download of package ‘httr’ failed
Any guidance would be greatly appreciated.
