在最新版本的RStudio和R版本（3.5.1 / 3.5.3）中安装软件包的问题

Question

I am unable to install packages (rtexttools and depend on maxent both lunch errors debt that the were removed recently from the CRAN repository) through latest version of RStudio and R Version.3.5.1 and 3.5.3.

I tried also installing them manually, format .tar, but nothing happened the the error remained.

The error:

install.packages("RTextTools")

Installing package into 'C:/Users/dramosd/Documents/R/win-library/3.5' (as 'lib' is unspecified)

Warning in install.packages : package 'RTextTools' is not available (for R version 3.5.3)

Answer 1

Some packages are not available to download via CRAN, In that case you can use below function to install R package directly from there github repo.

Try this-

library(devtools)
install_github("timjurka/RTextTools/RTextTools") 

**Note- RTextTools is no longer actively maintained by developer. So, above method may not work.

Please check there website for more info-
