在R启动的时候,会自动source工作目录下的.Rprofile文件;Mac和Linux中默认的路径为$HOME,Windows中默认路径为C:\Users\用户名\Documents
把代码框中的代码复制.Rprofile文件中,如果.Rprofile不存在则需要新建;
using函数是我写在.Rprofile中的函数,因此每次打开R就能使用,using的功能是一次加载多个包,并且使用了suppressPackageStartupMessages函数,因此不会显示加载包过程中的信息。
# library
using <- function(...) {
packages <- as.character(match.call(expand.dots = FALSE)[[2]])
if (length(packages) == 0) {
return(invisible())
}
# Attempt to load packages making note of which don't load
loaded <- sapply(packages, function(x) {
# Try to load package
if (suppressPackageStartupMessages(require(x, character.only = TRUE, quietly = TRUE))) {
return(TRUE)
}
# Couldn't load
return(FALSE)
})
# Give a warning if some packags couldn't be loaded
if (!all(loaded)) {
failed <- packages[!loaded]
warning("\n Failed to load: ", paste(failed, collapse = ", "))
}
return(invisible(loaded))
}
# pre-library packages
using(pak, data.table, stringr, tibble, dplyr, tidyr, purrr, magrittr)
# mirrors
pak::repo_add(
CRAN = "https://mirrors.tuna.tsinghua.edu.cn/CRAN",
BioCsoft = "https://mirrors.tuna.tsinghua.edu.cn/bioconductor/packages/3.18/bioc",
BioCann = "https://mirrors.tuna.tsinghua.edu.cn/bioconductor/packages/3.18/data/annotation",
BioCexp = "https://mirrors.tuna.tsinghua.edu.cn/bioconductor/packages/3.18/data/experiment",
BioCworkflows = "https://mirrors.tuna.tsinghua.edu.cn/bioconductor/packages/3.18/workflows"
)
pak添加镜像
写在.Rprofile文件中
pak安装R包
使用pak管理R包,可以从Bioconductor、CRAN、Github、本地、URL安装R包,解决了R包安装需要多个不同R包去安装的问题。
除了本地安装使用local_install函数,其他几种安装方式都是用pkg_install函数
install.packages("pak")
using(pak)
CRAN
pak::pkg_install("dplyr")
Bioconductor
pak::pkg_install("ComplexHeatmap")
GitHub
