Hello stevenworthington,
I am not used to R, i am unix administrator. Could you please help to execute r packages in one shot. ( very Urgent)
As i dont have internet to the server, so cran not possble. I download the files locally and perform by this way in R console,

install.packages("/tmp/R_binaries_gz/Rsolnp_1.16.tar.gz", repos=NULL, type="source")

i have to change the package name and execute it manually for the rest of the package.

Thanks in Advance :)

Using R 3.2.3 on linux. The if (length(new.pkg)) test is always returning true, so the packages are all being reinstalled even when not necessary.

You can check and use lubripack package which is an s3 package on github. It is a bit easier and robust to use. github/espanta/lubripack -> here

Thanks, I've changed it a little and added top 100 packages. This was useful in a new fresh R installation I had to do. You might have failing packages depending on your system features or installed libraries. You might have to run it several times to install every package. Best

ipak <- function(pkg){
new.pkg <- pkg[!(pkg %in% installed.packages()[, "Package"])]
if (length(new.pkg))
install.packages(new.pkg, dependencies = TRUE)
sapply(pkg, require, character.only = TRUE)
packages <- c("ggplot2", "plyr", "reshape2", "RColorBrewer", "scales", "grid", c("plyr","digest","ggplot2","colorspace","stringr","RColorBrewer","reshape2","zoo","proto","scales","car","dichromat","gtable","munsell","labeling","Hmisc","rJava","mvtnorm","bitops","rgl","foreign","XML","lattice","e1071","gtools","sp","gdata","Rcpp","MASS","Matrix","lmtest","survival","caTools","multcomp","RCurl","knitr","xtable","xts","rpart","evaluate","RODBC","tseries","DBI","nlme","lme4","reshape","sandwich","leaps","gplots","abind","randomForest","Rcmdr","coda","maps","igraph","formatR","maptools","RSQLite","psych","KernSmooth","rgdal","RcppArmadillo","effects","sem","vcd","XLConnect","markdown","timeSeries","timeDate","RJSONIO","cluster","scatterplot3d","nnet","fBasics","forecast","quantreg","foreach","chron","plotrix","matrixcalc","aplpack","strucchange","iterators","mgcv","kernlab","SparseM","tree","robustbase","vegan","devtools","latticeExtra","modeltools","xlsx","slam","TTR","quantmod","relimp","akima","memoise"))

I am new to R.
We have a setup like, R (R is on Linux) is connected to SAP HANA. We have a request to install R-packages.
Packages: rJava,RODBC,RJDBC,DBI,monmlp,AMORE,pmml,XML,arules,caret,reshape,plyr,foreach,iterators,adabag,randomForest,ggplot2

Can some one please let us know, How to install them.
As far i know, To install R- packages - i need to download R-package and install them by using command : Ex:
install.packages("/tmp/R_binaries_gz/Rsolnp_1.16.tar.gz", repos=NULL, type="source")

Here are my question now:

  1. How to check package is installed or not in Linux.
  2. How to check list of packages installed in R-server - Linux.
  3. Where to check error logs.
  4. How to uninstall the R- package in Linux.
  5. Is this package saved in to File syste level or Database level. In our case Database is HANA.

Could some one be kind and help me here.

I've been using this for a few years now and just though that it might be cool if there could be a version of this that uses install_github or any of the devtools::install_ for packages as I find myself using this most often for my work.

I will try and figure out how to do that but I don't have much time to dedicate to it which is why I am tossing the idea out here for anyone else to tackle if they think they can do it!

Agian, thank you @stevenworthington for speeding up my workflow with this function 😄



Well I procrastinated at work and made a version of this that does this now found here. I haven't tested it for options other than install_method = "github" and install_method = "base" so feel free to check it out and change it as needed!

I love this function!! Made an edit to install and/or load GitHub packages

ipak_gh <- function(pkg){
    new.pkg <- pkg[!(sub('.*/', '', pkg) %in% installed.packages()[, "Package"])]
    if (length(new.pkg)) 
        remotes::install_github(new.pkg, dependencies = TRUE)
    sapply(sub('.*/', '', pkg), require, character.only = TRUE)

# Example
ipak_gh(c("lmullen/gender", "mtennekes/tmap", "jalvesaq/colorout", "timathomas/neighborhood", "arthurgailes/rsegregation"))
