为什么安装PCNM程序包失败呢?
在R或Rstudio中敲入代码出现警告:
install.packages("PCNM")
Warning in install.packages :
package ‘PCNM’ is not available (for R version 3.2.2)
后来在 R-Forge网站http://r-forge.r-project.org/R/?group_id=195找到PCNM程序包,但网站页面显示如下: MEM spatial eigenfunction and principal coordinate analyses
Spatial eigenfunction analysis by principal coordinates of neighbour matrices (PCNM) and principal coordinate analysis.
Version: 2.1-4 | Last change: 2015-07-13 14:41:21+02 | Rev.: 128 Download:(.tar.gz) | (.zip) | Build status: Failed to build R install command:install.packages("PCNM", repos="http://R-Forge.R-project.org") 请问这是为什么?我该如何下载此程序包并安装?谢谢!
你好,为什么下载之后添加还是失败呢?Warning in install.packages :
cannot open compressed file 'PCNM_2.1-2/DESCRIPTION', probable reason 'No such file or directory'
Error in install.packages : cannot open the connection
