Failed with error: ‘‘operator’ is not a valid installed package

Question

Currently I am having problems with loading an R package that I downloaded from github (https://github.com/hafen/operator). I downloaded the package and put it in my local R fol

Answer 1

I was facing the same issue with RTextTools, as RTextTools is now not available on CRAN.

I have Download RTextTools From Given Link


https://cran.r-project.org/src/contrib/Archive/RTextTools/

and copy RTextTools_1.4.2.tar.gz file in project root folder then run this command in project folder in terminal
"R CMD INSTALL RTextTools_1.4.2.tar.gz" After running this command I receive below error "ERROR: dependencies ‘SparseM’, ‘randomForest’, ‘tree’, ‘e1071’, ‘ipred’, ‘caTools’, ‘maxent’, ‘glmnet’, ‘tau’ are not available for package ‘RTextTools’"

Now install each dependencies from RStudio or RConsole (Any Editor used by you) by simply running this code

install.packages("caTools") Install all 9 required packages One By One (In My Case it was 9 Packages Dependencies required by RTextTools) all packages will be installed except 'maxent'

Now download maxent from the given link https://cran.r-project.org/src/contrib/Archive/maxent/

and copy maxent_1.3.3.1.tar file in project folder then run this command in project folder in terminal
"R CMD INSTALL maxent_1.3.3.1.tar"

Now For RTextTools Run this command again in Terminal "R CMD INSTALL RTextTools_1.4.2.tar.gz"

All is done Now..

But the Last Step is

Load the RTextTools using

library(RTextTools)

You will see one more Error: Load SparseM Now Loading SparseM use code below

library(SparseM)

and in the last Load RTextTools

library(RTextTools)
