我把程序包下载下来后,通过本地安装,提示为package ‘spectral.methods’ successfully unpacked and MD5 sums checked
可是我加载用library(spectral.methods)时,又提示,
Error in loadNamespace(i, c(lib.loc, .libPaths()), versionCheck = vI[]) :
there is no package called ‘sp'
Error: package or namespace load failed for ‘spectral.methods’
本人刚接触R语言,还望各位指教一下,感激不尽!
