在 R 中,如何自动安装使用我自己的包的包?
In R, how to install packages used my own package automatically?
这个问题靠近以下站点:
R - Importing 'xlsx' package to my own package doesn't work
我在某台电脑上制作了一个包,名称为aa
,安装正常
当我尝试在另一台计算机上安装自己的软件包时,出现以下错误消息:
==> Rcmd.exe INSTALL --no-multiarch --with-keep.source aa
* installing to library 'C:/Users/aaaaaaaaaaa/Documents/R/win-library/3.5'
ERROR: dependencies 'knitr', 'rstan', 'readxl', 'testdat', 'openxlsx', 'xlsx', 'gridExtra' are not available for package 'aa'
* removing 'C:/Users/aaaaaaaaaaa/Documents/R/win-library/3.5/aa'
In R CMD INSTALL
Exited with status 1.
在我的手上,一旦我安装了上述错误中描述的包 knitr
,然后错误消息如下,包 knitr
从中消失:
==> Rcmd.exe INSTALL --no-multiarch --with-keep.source aa
* installing to library 'C:/Users/aaaaaaaaaaa/Documents/R/win-library/3.5'
ERROR: dependencies 'rstan', 'readxl', 'testdat', 'openxlsx', 'xlsx', 'gridExtra' are not available for package 'aa'
* removing 'C:/Users/aaaaaaaaaaa/Documents/R/win-library/3.5/aa'
In R CMD INSTALL
Exited with status 1.
我想知道的是我自己的包里用到的包有没有自动安装
也许你可以尝试这样更简单的方法:
在您的 .R
文件
中添加以下代码
tryCatch({
library(knitr)
}, error = function(e) {
install.packages("knitr")
library(knitr)
})
或者
if("knitr" %in% installed.packages()[,1]){
library(knitr)
}else{
install.packages("knitr")
library(knitr)
}
