在存檔中安裝R包

Question

如何在Windows中安裝存檔中的軟件包？

http://cran.r-project.org/src/contrib/Archive/

當我嘗試安裝從存檔下載的tar.gz時，我收到以下錯誤：

 Error in gzfile(file, "r") : cannot open the connection In addition: Warning messages: 1: In unzip(zipname, exdir = dest) : error 1 in extracting from zip file 2: In gzfile(file, "r") : cannot open compressed file 'grasp_2.5-7.tar.gz/DESCRIPTION', probable reason 'No such file or directory' 

Answer 1

您可以下載源（tar.gz文件）並使用以下命令安裝它們：

R CMD INSTALL packagename.tar.gz

Answer 2

您可以在devtools嘗試install_version函數。 我們假設您要安裝ggplot2 0.8版本，可以將其稱為install_version('ggplot2', '0.8') 。 如果您使用的是Windows，則可以按照此處的說明從源代碼構建軟件包。

從存檔安裝圖形包時遇到同樣的問題。 另一個包（bnclasify）需要該包。

chooseBioCmirror() #select a different mirror than CRAN. This mirror may be #because is the one that has bnclasify in it (check this statement)

setRepositories() #In here you can select as many as you want to search for the       #package you need

ap <- available.packages() #list of all available packages

"graph" %in% rownames(ap) #search the package you need by name (return TRUE or #FALSE). 

install.packages("graph", dependencies=TRUE) #if the last statement TRUE then #install the package like normally
