dependency ‘slam’ is not available when installing TM package

Question

I was able to use the library(tm) in r without problem until today, when loading tm shows:

library(tm)

Answer 1

For R-version 3.2.3, following worked fine as mentioned in this link and it suggests this works for R-version 3.3.0 as well:

#install devtools if you have not installed 
install.packages('devtools')
library(devtools)

slam_url <- "https://cran.r-project.org/src/contrib/Archive/slam/slam_0.1-37.tar.gz"
install_url(slam_url)
